Introduction
Radiographic findings of the shoulder joint have been reported in patients with rotator cuff tear, greater tuberosity changes are among the most reported.The aim of this work is to assess the greater tuberosity sclerosis as a radiographic sign of rotator cuff tear and its relation to the tear size.Patients and methods
This study was conducted from July 2009 until May 2013 in a retrospective fashion and included 425 patients, 250 females (58.8%) and 175 males (41.2%).Results
Sclerosis was detected in 398 cases out of 425 patients (93.6%). Of those, 360 (90%) were found to have a tear of the rotator cuff documented on M.R.I. Also greater tuberosity sclerosis being more prominent with large-sized tears. One hundred (23.5%) patients had been operated arthroscopically and a tear documented intraoperatively (Table 2).Conclusion
Greater tuberosity sclerosis has both high sensitivity and positive predictive value for rotator cuff tear. Also greater tuberosity sclerosis is found more with large-sized rotator cuff tears. 相似文献2.

Background
Lateral epicondylitis is referred to a degenerative disorder that affects the common extensor tendon (CET) where it attaches to the lateral epicondyle of the humerus. Nowadays, one of minimally invasive interventions is platelet-rich plasma (PRP) injection that had been explored in some controlled clinical studies to show its effectiveness in treating lateral epicondylitis through inducing inflammation rather than suppressing it.Objectives
The aim of our study was to investigate the effectiveness of ultrasound guided platelet-rich plasma (PRP) injection in treating chronic lateral epicondylitis in addition to identifying the potential sonographic morphological changes in the common extensor tendon (CET) after PRP injection.Results
Statistical analysis showed high significant improvement in all ultrasound findings of common extensor tendon (CET) including echotexture, thickness, cross section, partial tear and calcification in majority of patients.Conclusion
We concluded that US-guided platelet-rich plasma (PRP) injection for treatment of lateral epicondylitis was a safe, minimally invasive and effective procedure in improving the sonographic and pathological changes of common extensor tendon (CET). 相似文献3.

Background
Magnetic resonance (MR) provides detailed information for the depiction of shoulder lesions. It allows a unique anatomical and tissue characterization providing a detailed evaluation of the rotator cuff (RC) and the surrounding bones.Purpose
Our objective is to assess the diagnostic accuracy of MR in depiction of lesions encountered in shoulder impingement and rotator cuff (RC) degenerative lesions compared to shoulder arthroscopy.Patients and methods
This study included 28 patients with shoulder impingement for which conventional MR was done followed by arthroscopy. The results of MR were compared to the results of surgical repair.Results
MR was highly accurate in the diagnosis of full-thickness (FT) tears of the RC, showing 100% accuracy, 100% sensitivity, and 100% specificity. MR was capable of comprehensive evaluation of FT tears. MR had a high accuracy (96%) in the diagnosis of partial-thickness (PT) RC tears. It showed 100% specificity and 100% positive predictive value (PPV) with no false positive cases. MR revealed high specificity (100%) in the diagnosis of biceps abnormalities. It identified all the 20 negative cases that were confirmed surgically.Conclusion
Conventional MR plays an adequate role in evaluation of different lesions encountered in shoulder impingement and RC degenerative disorders. 相似文献5.

Background
The ankle is frequently injured in trauma, overuse syndrome and inflammatory processes. Different imaging modalities assess the ankle, including plain radiography, computed tomography (CT), magnetic resonance imaging (MRI), and ultrasonography (US).Purpose
Our objective is to assess the role of high resolution US as a valuable tool in the depiction of causes of ankle joint pain.Patients and methods
The study included 28 patients presented with ankle pain ranging in age from 17 to 60 years. They were examined by US and findings were correlated with MRI.Results
US was capable to detect various lesions (synovitis, arthritis, plantar fasciitis, tendon and ligamentous lesions). It had a sensitivity of 95.4%, a specificity of 83.3% and an overall accuracy of 92.8%. US had a limited value in detection of avascular necrosis (AVN), bone marrow oedema and fractures.Conclusion
US can be used as a first step diagnostic tool in cases of ankle pain. MRI should be spared to cases with negative or equivocal US findings. 相似文献6.

Objective
To assess the diagnostic accuracy of diffusion weighted imaging (DWI-MRI) being a non-contrast based MR sequence versus dynamic contrast enhanced MRI (DCE-MRI) in the preoperative loco-regional staging of the cervical carcinoma.Methodology
Fifty cases of proved cancer cervix prior staging subjected to dynamic post contrast technique: one pre-and six post contrast phases (40?s each). DWI was scanned using different b values and ADC values were measured.Results
DWI was the most accurate in staging operable cases (93.3%).Parametrial infiltration was overestimated in 3 cases versus 4 cases in DCE-MR. DWI showed 100% sensitivity, positive predictive value and accuracy in the assessment of locally advanced carcinomas. In metastatic lymph nodes, DCE-MR showed the least accuracy of 86%.Conclusion
DWI is helpful in discriminating local from locally advanced cervical carcinomas. DCE-MR can delineate cervical carcinomas confined to the uterus and exclude bladder/rectal invasion. 相似文献8.

Background
Ninety percent of hepatic cancers are hepatocellular carcinomas (HCC) which have an unfavorable prognosis. HCC is a hypervascular tumor supplied mainly by the hepatic artery. It has a higher blood supply than the surrounding hepatic tissue due to neovascularization. Computed tomography with perfusion imaging (CTP) is a non invasive tool which quantifies the blood flow parameters of HCC and compares it to the surrounding tissue.Purpose
To prove that CTP is a valuable diagnostic tool in diagnosis of HCC and posttherapeutic assessment.Patients and methods
One hundred and twenty-six HCC patients with 150 focal lesions are enrolled this study. Perfusion parameters are quantified and results are compared to those of triphasic CT.Results
CTP detected 141 lesions with 94% sensitivity and 40% specificity with elevated arterial perfusion (AP) and perfusion index (PI) with low portal flow (PF). It missed 5 lesions because of their hypovascularity and 4 lesions following radiofrequency ablation (RFA) and trans arterial chemo embolization (TACE).Conclusion
CTP is a safe and specific imaging tool for diagnosis and assessment of therapeutic interventional procedures in HCC. 相似文献9.

Objectives
To assess diagnostic benefits of filling of the rectum with ultrasound gel during MR assessment of rectal cancer and the pitfalls that occurs due to rectal distention.Materials/methods
40 patients presented with rectal cancer for either initial MR staging or for assessment after neoadjuvent chemoradiotherapy using ultrasound transmission gel as a contrast for rectal filling.Results
MR with gel rectal filling showed better depiction in all patients with small tumors than in non filling of the rectum. The filling of rectum with gel increased the distance of the lower tumor border from the anal verge however it showed better assessment of the site of the fixed tumor lower edge in all cases of pedunculated tumor masses. Also rectal filling decreases the distance from the perirectal fascia which may affect the CRM.Conclusions
MR with rectal gel filling is useful in assessment of cases with rectal cancer and by combining empty rectum & distended rectum in the same study we can get the benefits & avoid the pitfalls by correlating the images in both techniques.Clinical Relevance/Application This study helped in assessment of patients with rectal cancer either referred for initial MR staging or for assessment after neoadjuvent chemoradiotherapy. 相似文献11.

Background
Urinary tract injuries occur in 3–10% of abdominal trauma. Early recognition and diagnosis of ruptured bladder is essential to lower this mortality rate. CT is the method of choice for the evaluation of patients with blunt or penetrating abdominal and/or pelvic trauma. Imaging in patients with suspected bladder injury with CT cystography may be performed using either an intravenous or retrograde technique.Aim of work
The aim was to evaluate the role of CT in diagnosing traumatic urinary bladder injuries.Materials and methods
The study was carried out on 32 patients with suspected traumatic urinary bladder injury. All patients were subjected to contrast-enhanced CT study and classified according to Sandler et al. classification of urinary bladder injuries.Results
All patients were classified according to the type of the encountered urinary bladder trauma. Type I injury was diagnosed in 3.1% of patients, type II in 18.8%, type III in 3.1%, type IVa in 12.5%, type IVb in 43.7% and type V in 18.8%. 21.8% of patients were managed conservatively, while 78.2% of patients underwent surgical repair.Conclusion
CECT well demonstrated traumatic urinary bladder injuries. 相似文献12.

Objective
The goal of this study was to highlight the role of follow up CT angiography examination in detection and classification of endoleaks and therefore deciding management plans after endovascular abdominal aortic aneurysm repair (EVAR).Patients and Methods
During one year duration 37 patients who have been operated were examined 1 and 6 months after EVAR as routine follow up. The images obtained were interpreted and reconstructed using dedicated software and work stations.Results
Out of 37 cases, 14 cases (37.8%) had positive endoleaks and 23 cases (62.2%) were free. Type I endoleak was diagnosed in 4 cases (10.8%) and type II endoleaks was diagnosed in 10 cases (27%) as 7 cases (18.9%) showed leak through lumbar arteries and 3 cases (8.1%) showed leak through the inferior mesenteric arteries.Conclusion
CT angiography can accurately detect and classify endoleaks and thus determine line of treatment. Endoleaks are often asymptomatic and may become evident intra operatively or many years after the operation, therefore lifelong imaging supervision is necessary. 相似文献13.

Objective
The prognosis of different histologic subtypes of RCC varies and affects management. Patients with chromophobe or papillary RCC have better prognosis than those with clear cell RCC. The aim of our work was to study the utility of DCE and DWI in the preoperative prediction of renal cell carcinoma subtypes, using histopathology as a gold standard method of diagnosis.Patients and methods
Thirty five patients with 38 renal masses were included in the study. All had DCE MRI studies with DWI sequences, CER and ADC values calculation for normal and diseased renal tissues.Results
The Mean ADC value of normal renal parenchyma was significantly higher than RCC. The CER and ADC values for Clear cell RCC were higher than Papillary and Chromophobe RCC. No statistically significant difference was found between the CER & ADC values for Papillary and Chromophobe RCC. CER & ADC values of clear RCC were higher than non clear RCC.Conclusions
DCE MRI in addition to DWI & ADC appears as a very helpful imaging tool in the differentiation between clear cell and non-clear cell RCCs. 相似文献14.

Aim
The aim of this study is to evaluate the role of high resolution ultrasonography (HRUS) of the hip in premature neonates admitted to the neonatal intensive care unit (NICU) in diagnosis of septic hip arthritis.Patients and methods
This prospective study was done for twenty premature neonates having clinical and laboratory findings compatible with the diagnosis of acute septic arthritis. They were subjected to HRUS of the hip as well as US-guided aspiration and analysis of synovial fluid.Results
Hip ultrasonography showed synovial fluid containing echoes in twelve patients and was clear in six patients. Joint capsule was thickened in fourteen patients. Seventeen patients had sonographic features of septic arthritis. The sensitivity of HRUS was 93.8%, specificity 50%, positive predictive value 88.2%, negative predictive value 66.7% and the accuracy was 85%.Conclusion
HRUS is beneficial in early diagnosis of septic hip arthritis in premature neonates admitted to the NICU. It is an easy, available and rapid procedure. 相似文献15.

The aim of the study
Is to compare the role of minimum intensity projection (MinIP) images with that of volumetric high resolution computed tomography (HRCT) images in the diagnosis of interstitial lung diseases (ILD).Patients and methods
180 patients (149 females and 31 males) were included in this prospective study that took place over a duration of two and half years. All patients underwent HRCT and MinIP images. The positive findings were compared recording which technique was better and if MinIP adds a value in reaching an accurate diagnosis.Results
MinIP images showed better visualization of traction bronchiectasis, ground glass opacities and mosaic attenuation pattern, as well as, the cystic lung changes seen in LAM. While MinIP did not add a significant value in thick-walled cystic changes e.g.: honeycombing.Conclusion
MinIP is one of the multiplanar techniques of HRCT that proved throughout our study to be an informative complementary tool increasing the observer confidence and agreement regarding some findings as compared with HRCT alone. 相似文献16.

Objective
To compare the accuracy of 2D and 3D CT measurements of femoral anteversion angle, in pediatric patients with developmental hip dysplasia.Materials and methods
Twenty patients (20 hips) with unilateral non syndromic DDH were studies. CT scans were performed using a 16 slice CT scanner to measure the femoral anteversion angle (FAVA) using 2D & 3D techniques. Findings were correlated with the intra operative measurements.Results
There was a significant difference between 2D & 3D methods. Results of clinical assessment were comparable to results of 3D CT assessment which range from 30 to 50° with a mean of 37.5°. Mean percent difference between 3D and intra operative measurement of FAVA was significantly lower than the corresponding value between 2D and intraoperative measurement of FAVA.Conclusion
3D is more accurate than 2D in measuring the degree of FAVA in DDH patients. It is easily applied and rapid and doesn't require sophisticated software. 相似文献17.

Purpose
To evaluate the role of 3-dimensional (3DUS) and 4-dimensional ultrasound (4DUS) in detection of fetal causes of oligohydraminos.Patients and methods
250 pregnant females (Age range from 19 to 45?years, mean age 33?years) were referred from the Obstetrics and Gynecology Department with oligohydraminos for fetal anomaly scan and Doppler study.Results
111 of the 250 patients were primi- gravida and 139 were multigravida. Consanguinity was positive in 106 females. In 100 patients, the examined fetuses were abnormal, TORCH infection was +ve in 25 patients. In 150 cases no fetal cause was detected for oligohydraminos. Autosomal recessive polycystic kidney disease (ARPKD, Potter type I) was the commonest fetal cause in our group detected in 24 of 100 patients followed by bilateral multicystic dysplastic kidney (Potter type II) in 19 patients, unilateral renal aplasia was the least cause in our study.Conclusion
3-dimensional and 4-imensional ultrasound and anomaly scan are effective in detecting fetal causes of oligohydraminos and early determination of lethal causes. 相似文献19.

Background
MS plaques display different pattern of enhancement with variable clinical course. The purpose is to assess the role of ADC value as a predictive for MS histologic changes with different enhancing pattern and its correlation with disease activity.Patients and methods
This prospective study included 28 chronic MS patients with 75 lesions, subjected for magnetic resonance imaging and ADC value measurement of the plaques and normally appearing white matter (NAWM) to be correlated with that of normal white matter (NWM) in 20 healthy controls.Results
T1-Hypointense and confluent lesions had statistical significant higher mean ADC value relative to the isointense and discrete lesions. Statistical significance difference was detected between mean ADC value of homogeneously enhancing lesions (HELs) and ring enhancing lesions (RELs) and between HELs and non-enhancing lesions (NELs), but no difference between NELs and RELs. Statistical significance difference was detected between ADC of NAWM relative to NWM of healthy controls.Conclusion
ADC value predicts histological changes in MS lesions. Pattern of enhancement doesn't correlate with neurologic deficits but ADC value is more valuable in assessing the disease activity. 相似文献20.
