Purpose
This study aimed at comparing the diagnostic accuracy of ultrasonography (US) and magnetic resonance imaging (MRI) for the detection of joint effusion of the knee.Methods
For this retrospective study, approbation by the institutional review board was not required, and written informed consent from the patients was waived. One hundred and fifty-eight patients (83 men and 75 women; median age 41.2 years; age range 13–81 years) who underwent US and MRI of the knee were included in the study. The sensitivity and specificity of US with respect to MRI in the evaluation of the effusion of the knee and in each recess were compared.Results
In evaluating joint effusion of the knee, compared with MRI, US correctly identified 78 of 96 patients with joint effusion, showing a sensitivity of 81.3 % and a specificity of 100 %, with a positive predictive value (PPV) of 100 % and a negative predictive value (NPV) of 77.5 % (p value = 0.001). Various results were obtained comparing ultrasound with MRI, regarding the various recesses.Conclusion
US showed high specificity and sensitivity in diagnosing knee joint effusion and could be used in patients who cannot undergo MRI.Electronic supplementary material

Purpose
To assess pattern of articular disc displacement in patients with internal derangement (ID) of temporomandibular joint (TMJ) with ultrasound.Materials and methods
Prospective study was conducted upon 40 TMJ of 20 patients (3 male, 17 female with mean age of 26.1 years) with ID of TMJ. They underwent high-resolution ultrasound and MR imaging of TMJ. The MR images were used as the gold standard for calculating sensitivity, specificity, accuracy, positive predictive value (PPV), negative predictive value (NPV), positive likelihood ratio (PLR), and negative likelihood ratio (NLR) of ultrasound for diagnosis of anterior or sideway displacement of the disc.Results
The anterior displaced disc was seen in 26 joints at MR and 22 joints at ultrasound. The diagnostic efficacy of ultrasound for anterior displacement has sensitivity of 79.3 %, specificity of 72.7 %, accuracy of 77.5 %, PPV of 88.5 %, NPV of 57.1 %, PLR of 2.9 and NLR of 0.34. The sideway displacement of disc was seen in four joints at MR and three joints at ultrasound. The diagnostic efficacy of ultrasound for sideway displacement has a sensitivity of 75 %, specificity of 63.6 %, accuracy of 66.7 %, PPV of 42.8, NPV of 87.5 %, PLR of 2.06, and NLR of 0.39.Conclusion
We concluded that ultrasound is a non-invasive imaging modality used for assessment of anterior and sideway displacement of the articular disc in patients with ID of TMJ. 相似文献3.

Purpose
Total hip arthroplasty (THA) is a widespread option for treating hip osteoarthritis. Peri-prosthetic complications after THA represent a common event influencing patient outcome and costs. The purpose of this paper is to report the use of ultrasonography (US) to detect peri-prosthetic complications in symptomatic patients who underwent THA.Methods
We retrospectively reviewed the records of patients with THA who underwent imaging evaluation between January 2009 and December 2012 at two different institutions. We evaluated the presence/absence of superficial and/or deep peri-prosthetic collections as well as the presence/absence of a cutaneous sinus tract. For patients who underwent both MRI and US, a concordance correlation analysis between US and MR findings was performed.Results
In the reference period, 532 symptomatic patients (mean age ± standard deviation 74 ± 12 years) underwent X-ray and MRI examinations for suspected peri-prosthetic complications. Among them, 111 (20.9 %) underwent also US. Overall, 108 patients underwent both US and MRI. US findings included 67 superficial collections, 48 subcutaneous fistulas, 74 deep peri-prosthetic collections. Twenty-four patients had solid, mass-like peri-prosthetic collections. In 11 patients, no peri-prosthetic complications were seen. MRI findings included 68 superficial collections, 49 subcutaneous fistulas, 79 deep peri-prosthetic collections. Twenty-four patients had solid, mass-like peri-prosthetic collections. In four patients, no peri-prosthetic complications were seen. Concordance analysis between US and MRI findings showed almost perfect agreement (k ≥ 0.89).Conclusion
US is an efficient and practical imaging modality to evaluate peri-prosthetic complications in patients with THA, being almost comparable to MRI in detecting and characterizing these complications. 相似文献4.

Objective
It was the aim of this study to compare the efficacy of ozone therapy and drug treatment in patients with painful temporomandibular joint (TMJ) disorder (TMD).Subjects and Methods
A total of 63 patients with TMD were enrolled; 33 were treated with bio-oxidative therapy and 30 with a ketoprofen tablet thiocolchicoside capsule 2 × 1 for 7 days. Maximum voluntary interincisal mouth opening (MMO) was measured in millimeters using a scale and recorded during the pre- and posttreatment periods. The patients evaluated their subjective pain using a visual analogue scale (VAS). Data were analyzed using the Mann-Whitney U test, the Kolmogorov-Smirnov test, and the independent t test.Results
The mean MMO of the group that received ozone therapy during the pretreatment period was 46.51 ± 8.2 mm, and it immediately increased to 48.78 ± 7.5 mm after 1 week of ozone therapy, which was statistically significant (p = 0.04). For those who received medication, the mean MMO during the pretreatment period was 46.30 mm, and at the end of 1 week it was 46.9 mm. In the ozone group, 29% of patients showed a gradual decrease in their VAS pain scores compared to pretreatment values (6.3 ± 2.1 to 3.0 ± 2.2). In the medication group, 24% of patients showed a significant decrease in VAS pain scores during the follow-up period (6.9 ± 1.4 to 5.0 ± 1.5).Conclusion
This study showed that bio-oxidative therapy was a more effective treatment than medication therapy for relieving TMJ pain.Key Words: Ozone therapy, High-frequency bio-oxidative therapy, Temporomandibular disorder, Pain 相似文献5.
Purpose
To assess the diagnostic accuracy and inter-observer variability of ultrasound (US) in recognizing signs of intra or extra-capsular rupture of silicone breast implants by using the magnetic resonance imaging (MRI) findings as the reference standard.Methods
150 patients for a total of 300 implants underwent breast US and subsequently MR examination searching for signs of intra or extra-capsular rupture. Sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), and diagnostic accuracy were calculated for breast US having MRI findings as the reference standard. Cohen’s kappa statistics was used in order to assess inter-observer agreement for US.Results
170/300 (57 %) implant ruptures were detected at US (intra-capsular n = 110, extra-capsular n = 60). By comparing US findings with MR results, overall sensitivity, specificity, accuracy, PPV, and NPV of 79, 63, 70, 65, and 77 %, respectively, were found for breast US. In case of intra-capsular rupture, sensitivity, specificity, accuracy, PPV, and NPV of 63, 63, 63, 45, and 77 %, respectively, were obtained; 100 % values were found for extra-capsular rupture US diagnosis.Conclusion
US can be used as the first examination in patients with breast implants. US intra-capsular rupture detection requires further evaluation by MRI; in case of extra-capsular rupture US diagnosis, surgical implant removal could be proposed without further investigations. 相似文献6.
Background
The sacroiliac joint is one of the sources of chronic lower back pain. Intra-articular injections of anesthetic drugs and/or steroids are currently used in these cases for diagnostic and therapeutic purposes. However, given the anatomic and functional complexity of the joint, imaging guidance is mandatory during such procedures. In this context, the technique of fusing images obtained with two different modalities can often overcome the limitations and enhance the advantages of single-modality guidance.Aim
The aim of this study was to evaluate the technique of ultrasound (US)–magnetic resonance (MR) image fusion to guide intra-articular injections of drugs into the sacroiliac joint.Materials and methods
We evaluated seven sacroiliac joints in six patients with sacroiliac pain syndrome (four females, two males; mean age 59 years; range 46–76 years). Five were candidates for radiofrequency thermolysis, and a therapeutic nerve block was performed in the sixth. Using the volume navigation system, we fused three-dimensional MR images with simultaneously acquired real-time ultrasound images and used them to guide the intra-articular injections.Results
In all patients, spatial accuracy was considered excellent, with definition of registration errors of less than 3 mm. The diagnostic blocks produced positive results in all patients with 80 % reductions in pain (measured with a Numerical Rating Scale, NRS) relative to baseline. The patient who underwent the therapeutic nerve block experienced complete resolution of symptoms that has been maintained over time. There were no complications.Conclusions
US–MR imaging fusion guidance of sacroiliac joint injections is feasible and effective, in accordance with the data in the literature. The use of the MR for three-dimensional imaging eliminates the risk of radiation exposure. 相似文献7.

Aim
The aim of this study was to review our 18-year experience in the treatment of viable hydatid liver cysts (HLCs) with double percutaneous aspiration and ethanol injection (D-PAI) and to provide indications for the clinical management of HLCs.Materials and methods
From January 1989 to December 2007, 127 patients (100 males; 13–80 years) with 184 viable HLCs (137 univesicular, 47 multivesicular; 2.8–20 cm) underwent D-PAI.Results
Ultrasonography (US) showed complete disappearance of 125/184 (68%) cysts; in the remaining 59 cases, an inactive solid (37 cases, 20%) or liquid pattern (22 cases, 12%) was observed with volume decreases of 50–80%. The final US pattern was unmodified during the follow-up in 96.8%. Local recurrences were observed in 5 patients (3.9%): 4 patients with 8 multivesicular cysts and 1 patient with a bilocular cyst (with a solid pattern on US) that ruptured into the biliary tree 2 years after the procedure and disappeared after endoscopic sphincterectomy. The mortality rate was 0.8%, and the overall morbidity was 8.6%. The mean hospital stay was 2.9 days. The time of healing for smaller cysts (<5 cm) was shorter than that of large cysts (≥5 cm) (P < 0.001).Conclusion
Our long-term results confirm the high effectiveness of D-PAI in the treatment of HLCs. These results suggest that multilocular cysts require closer follow-up than unilocular cysts. 相似文献8.

Background
There is little research on how the amount of shoulder joint range of motion, specifically glenohumeral rotation, may be related to the muscle strength of the rotator cuff muscles. A long held belief is that a joint with excessive range of motion needs sufficient muscular strength for stability. However, no studies have examined this concept.Purpose
The purpose of this study was to see if total arc of glenohumeral joint rotation (External rotation [ER]+Internal rotation [IR]) could predict peak isometric muscle strength of the IR or ER muscles of the shoulder.Study Design
Cross‐sectional study designMethods
Fifty‐three participants (41 females, 12 males) participated in the study. Passive glenohumeral joint internal rotation and external rotation motion was measured for each participant with a standard goniometer. Isometric muscle force of the ER and IR muscles were tested using a handheld dynamometer in three positions: end range ER, neutral 0°, and end range IR. Data were analyzed using a non‐parametric tree based regression method (CART) and then cross‐validated.Results
The results showed that those with an increased total arc of motion of glenohumeral rotation (greater than 165.0°) had less muscle isometric muscle strength in all tests positions than those with less glenohumeral rotation.Conclusion
Decreased force of the ER and IR muscles of the shoulder was noted in those with increased total arc glenohumeral rotation ( > 165.0°), specifically those with increased glenohumeral internal rotation ( > 80.0°) when compared to those with glenohumeral rotation ( < 165.0°) and glenohumeral internal rotation ( < 80.0°). Future studies should include more males and attempt to develop strategies to assist those with larger excursions of shoulder rotation who may be at risk of developing shoulder problems.Level of Evidence

Purpose
To evaluate the feasibility and utility of serial measuring of the optic nerve sheath diameter beyond the hyperacute and acute stage of intracerebral hemorrhage (ICH).Methods
Four patients with extensive ICH in the left basal ganglia were followed using ultrasound (US) and cerebral CT scans.Results
Optic nerve sheath diameter values assessed beyond the acute stage of ICH showed a high correlation (ρ = 0.84, p = 0.0022) with midline shift of the third ventricle seen on CT scans.Conclusions
Optic nerve sonography can be useful to evaluate patients with extensive ICH beyond the acute stage and help monitoring clinical evolution in these patients, when ICP monitoring is not feasible. 相似文献10.

Purpose
To determine whether distraction-induced regeneration (DR) can be optimized based on consecutive ultrasound findings during the course of compression–distraction osteosynthesis (CDO).Materials and methods
Sixty-nine children ranging in age from 2 weeks to 15 years with congenital (37 patients) or acquired (32 patients) microgenia were treated with CDO. Radiological diagnostic studies included orthopantomography (OPG) and ultrasonography (US). The patients were divided into two groups: in group I a standard distraction rate (SDR) (1 mm/day) was used (33 patients, 47.8%); in group II (36 patients, 52.2%) individual distraction rates (IDR) were used based on US findings.Results
DR was classified as normotrophic, hypertrophic, or hypotrophic based on US findings. In group I, 11 (33.3%) of the patients presented normotrophic DR, 8 (24.2%) had hypertrophic DR, and in 14 (42.4%), the DR was hypotrophic. In group II, all patients presented normotrophic DR at the end of the treatment.Conclusion
US offers a unique opportunity to study DR development, and the results can be used to actively manage and optimize the osteogenesis process during mandibular CDO in children. 相似文献11.

Purpose
Because the cytotoxic potential of hydrophilic drugs like bleomycin (BLM) is restricted by its low membrane permeability, the application of low-intensity ultrasound (US) on growing tumor cells enhances intracellular delivery of BLM after intratumoral administration, thereby potentiating its cytotoxicity. In the present study, the in vivo cell membrane permeability enhancement with US (1 MHz, 2, 5, and 10 min, ISPTA = 2 W/cm2) is compared with the murine model of breast adenocarcinoma in BALB/c mice.Methods
Tumor induction was performed through a homograft surgery procedure. Mice were anesthetized before putting them in sonication situations. Sonications were done in an aquarium. Seven groups of the tumor-bearing mice, each consisting of eight mice, were sonicated without or after intratumoral injection of 0.1 ml BLM at different exposure times. The tumor volume was evaluated to assess the growth process by use of a digital caliper.Results
The results show that the BLM control group has a significant difference with BLM plus 10 min US on day 2 (p < 0.05). There is a significant difference between 2- and 10-min sonication on days 8 and 10 also. The difference between the Only US group and the other groups except Sham US was significant too (p < 0.05). Significant differences were seen only between the BLM plus US groups with Sham US and Only US control groups.Conclusion
It has been concluded that for significant permeabilization of the cell membrane, sonication time for more than 10 min is required. Significant difference between the Only US and other groups indicates that US has a promoting effect on cell division procedure, in spite of the no-carcinogen effect of the US. 相似文献12.
Background and purpose
Sonoelastography (SE) is a new technique that can assess differences in tissue stiffness. This study investigated the performance of SE for the differentiation of supraspinatus (SSP) tendon alterations of tendinopathy compared to magnetic resonance imaging (MRI) and conventional ultrasonography (US).Methods
One hundred and eighteen consecutively registered patients with symptoms and MRI findings of SSP tendinopathy were assessed with US and SE. Coronal images of the SSP tendon were obtained using US and SE. Increased signal intensity on T2-weighted images in the coronal planes were graded according to the extent of the signal changes from ventral to dorsal. SE images were evaluated by reviewers using an experimentally proven color grading system.Results
Using SE, 7.6 % of the SSP tendons were categorized as grade 0, 30.5 % as grade 1, 19.5 % as grade 2, and 42.4 % as grade 3. Evaluation of the interobserver reliability of the SE findings showed “almost perfect agreement”, with a weighted kappa coefficient of 0.83. By comparing the MRI findings with the SE findings, grades of MRI and SE had a positive correlation (r = 0.829, p = <0.001). Furthermore, grades of US and SE also had a positive correlation (r = 0.723, p = <0.001).Conclusions
SE is valuable in the detection of the intratendinous and peritendinous alterations of the SSP tendon and has excellent interobserver reliability and excellent correlation with MRI findings and conventional ultrasonography findings. 相似文献13.

Background:
Changes in the proprioceptive system are associated with aging. Proprioception is important to maintaining and/or recovering balance and to reducing the risk of falls.Objective:
To compare the performance of young and active elderly adults in three proprioceptive tests.Method:
Twenty-one active elderly participants (66.9±5.5 years) and 21 healthy young participants (24.6±3.9 years) were evaluated in the following tests: perception of position of the ankle and hip joints, perceived force level of the ankle joint, and two-point discrimination of the sole of the foot.Results:
No differences (p>0.05) were found between groups for the joint position and perceived force level. On the other hand, the elderly participants showed lower sensitivity in the two-point discrimination (higher threshold) when compared to the young participants (p < 0.01).Conclusion:
Except for the cutaneous plantar sensitivity, the active elderly participants had maintained proprioception. Their physical activity status may explain similarities between groups for the joint position sense and perceived force level, however it may not be sufficient to prevent sensory degeneration with aging. 相似文献14.
Background
The diagnostic value of thoracic ultrasonography (US) has recently increased. Skilled sonographers with experience in pulmonary medicine have demonstrated the existence of US signs of chest pathology.Purpose
To detect US findings associated with infectious interstitial pneumonia that can be used to supplement other diagnostic tools.Materials and methods
Over a period of 5 years (2001–2006), 55 patients were referred to our ultrasonography units for evaluation of probable viral or viral-like infections of the respiratory tract. Each patient was subjected to a work-up that included clinical examination, blood tests, pulmonary function tests, bronchoscopy, chest radiographs, high-resolution computed tomography (HRCT), and thoracic US, which was performed under blinded conditions.Results
Based on the findings that emerged from the work-up described above, all 55 patients were diagnosed with interstitial pneumonia. Evaluation of the US scans for the signs of interstitial lung disease described by Lichtenstein revealed “comet-tail” artifacts in the anterolateral lung fields in 31 (56.36%) patients and mixed patterns consisting in increased density associated with ring-down artifacts in 24 (46.64%). Pleural involvement was also observed in 34 cases (61.82%).Conclusions
Thoracic US appears to be a useful adjunct to clinical, laboratory and radiological studies in patients suspected of having infectious interstitial pneumonia. 相似文献15.
Objective
Sonolastography (SE) technique is one of the new functional ultrasonic imaging techniques, which was developed in the past few years and can obtain the distributions of elasticity in tissues. Using magnetic resonance imaging (MRI) as the standard of reference, the purpose of this study was to evaluate the ability of SE to assess the fatty degeneration of suprasupinatus (SSP) and to compare it to the MRI and the conventional ultrasonography (US) findings.Materials and methods
The institutional review board approved the study, and a retrospective analysis between January 2013 and September 2013 was performed on 101 shoulders of 98 consecutive patients using MRI, US, and SE for the evaluation of shoulder lesion. Oblique sagittal images of SSP were obtained using SE. The SE images were evaluated by reviewers using an experimentally proven color grading system.Results
When comparing SE to standard MRI findings, the mean sensitivity of SE was 95.6 %, the specificity 87.5 %, and the accuracy 91.1 %. The interobserver reliability of the SE findings was “almost perfect agreement” with a weighted kappa coefficient of 0.81. On comparing MRI with the SE findings, the grades of MRI and SE have a positive correlation (r = 0.855, P = <0.001). Furthermore, the grades of US and SE also have a positive correlation (r = 0.793, P = <0.001).Conclusion
SE is valuable in the quantitative assessment of the severity of the fatty atrophy of the supraspinatus and has an excellent accuracy, an excellent correlation with MRI and the conventional US, and an excellent interobserver reliability. 相似文献16.

Objective
This study investigated the relationship between sleep adequacy and small dense low-density lipoprotein (sdLDL) in a Japanese population.Subjects and Methods
Clinical data, including atherosclerotic risk factors, in addition to the mean LDL particle size (LDL-PS) measured by gel electrophoresis, were evaluated in 136 community-dwelling female subjects (40-80 years old). The sleep status was self-reported and the subjects were divided into those who had inadequate sleep (≤6 or ≥9 h of sleep) and had adequate sleep (7-8 h).Results
The mean LDL-PS was significantly smaller in subjects with inadequate sleep [n = 68, 26.4 ± 0.4 (SD) nm] than in those with adequate sleep (n = 68, 26.6 ± 0.4 nm, p < 0.05). This difference remained significant and independent after adjusting for confounders (β = 0.15-0.19, p < 0.05).Conclusion
Sleep adequacy was associated with the presence of sdLDL, while the influence of the sleep status on LDL-PS was minor in this population. Further research on the associations among sleep, sdLDL and cardiovascular disease prevention is warranted.Key Words: Atherosclerosis, Small dense low-density lipoprotein, Sleep hygiene 相似文献17.

Introduction
Pilonidal disease is a benign anorectal inflammatory disease that involves the subcutaneous adipose tissue overlying the sacrococcygeal region.The aim of the work
The current study aimed to assess the value of preoperative evaluation of pilonidal disease and the exclusion of perianal sepsis using superficial parts ultrasonography and endoanal ultrasound.Methodology
Referred 30 patients were clinically diagnosed as pilonidal disease, all were examined with superficial parts ultrasonography and if the disease was extending to the perianal region further endoanal US was performed to exclude perianal sepsis.Results
7 patients showed subcutaneous abscesses and 23 patients showed pilonidal sinus tracts. Among patients with pilonidal sinus tracts, six tracts (26 %) seen as superficially situated, short narrow tracts with straight course, no side branches and with a blind end situated away from the anal canal wall. 2 (9 %) tracts showed vertical orientation and three tracts (13 %) were wide and deeply situated reaching the presacral fascia. 7 cases (30 %) showed branching pilonidal sinus tracts, two cases of them showed more than one external opening. 5 patients (22 %) showed abnormally long tracts seen reaching the perianal region.Conclusion
Ultrasonography is an available, inexpensive, safe imaging modality that yields a high degree of accuracy in evaluating pilonidal disease and in exclusion of perianal sepsis. 相似文献18.
Objective
The purpose of this study was to evaluate sonoelastography (SE) in the assessment of the long head of biceps tendon (LHBT) in patients with symptoms of biceps tendinitis or tendinosis and in patients without biceps lesion. The findings were compared with those obtained at clinical examination, using ultrasonography (US).Materials and methods
36 shoulders of 34 consecutively registered patients with clinical symptoms and US findings of biceps tendinitis or tendinosis, and 114 shoulders of 98 patients without biceps lesions were assessed with SE. Transverse and longitudinal images of LHBT were obtained using SE. SE images were evaluated by reviewers using an experimentally proven color grading system.Results
The transverse images of SE showed a mean sensitivity of 69.4 %, a mean specificity of 95.6 % and a mean accuracy of 89.3 %. Good correlation of conventional ultrasound findings was found (p < 0.001, r = 0.763). The longitudinal images of SE showed a mean sensitivity of 94.4 %, a mean specificity of 92.1 % and a mean accuracy of 92.7 %. Good correlation of conventional ultrasound findings was found (p < 0.001, r = 0.585). Inter-observer reliability of SE was in “almost perfect agreement” with a weighted kappa coefficient of 0.84.Conclusions
SE has potential to be clinically useful in the detection of the intratendinous and peritendinous alterations of LHBT and has excellent accuracy and excellent correlation with conventional ultrasound findings. 相似文献19.

Objective
The purpose of this study was to investigate autonomic nervous system dysfunction by measuring pupil sizes in pediatric patients with allergic rhinitis.Subjects and Methods
The study group consisted of 60 children (28 girls and 32 boys) who were age and gender matched with the control group, which also consisted of 60 children (26 girls and 34 boys). The diagnosis of allergic rhinitis was based on the history, physical examination and skin prick test performed by an allergologist. Pupil diameter measurements were performed using the pupillometer incorporated in the NİDEK OPD-Scan.Results
In the allergic rhinitis group, mean photopic and mesopic pupil diameters were 3.52 ± 0.07 and 5.98 ± 0.21, respectively, while in the control group, corresponding measurements were 4.03 ± 0.18 and 6.55 ± 0.16. There was a significant difference for photopic and mesopic pupil diameter between the groups (p < 0.001).Conclusion
This study showed that the pupil size in response to a light stimulus in children with allergic rhinitis was smaller than that of the control group and may indicate parasympathetic hyperactivity and sympathetic hypoactivity.Key Words: Allergic rhinitis, Children, Pupil diameter, Autonomic nervous system 相似文献20.
