Purpose
To highlight the relationship between coraco-humeral distance and subscapularis tendon tear.Material and methods
Sixty-two shoulder MRI studies were examined. Twenty-two patients had partial or complete tear of subscapularis tendon and forty shoulder as a control group. Axial and oblique sagittal MR images were examined to measure the coraco-humeral distance followed by statistical analysis to correlate the distance with tendon tear.Results
A cut-off value of 8.25?mm for the coraco-humeral distance gave a sensitivity of 77.5% and specificity of 72.7% for subscapularis tendon tear.Conclusion
There is a well-known relationship between the coraco-humeral distance and the subscapularis tendon tear and its meticulous assessment in subjects with pain in the anterior shoulder region increases the diagnosis of subcoracoid impingement. 相似文献2.

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3.

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4.

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6.

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7.

Objective
This work aimed for using multislice computed tomography (MSCT) to map the bronchial tree and assess the exact site, direction, airway findings and bronchial measurements to guide trans-bronchial lung biopsy from an inaccessible lung lesion.Patients and methods
This study was carried on 26 patients. It was conducted in the Radiology Department, in collaboration with Chest Department, in the period from January 2015 to April 2016. All patients were subjected to Virtual Bronchographic (VB) examination and Trans-Bronchial lung biopsy (in selected cases guided by the VB results).Results
In this study, MSCT-VB maps guided the fiber-optic bronchoscopy in 30 bronchial lesions in 26 patients to the proper sampling site for different lung lesions with success rate 100% and CT maps were done, reaching 3rd to 7th order bronchial generation with mean distance from central bronchi was 21.3?mm and mean target bronchial diameter was 1.9?mm. Right sided lesions encountered in 57.7% and left sided lesions in 42.3% with the most common segmental affection was the right upper lobe in 36.7% of bronchial lesions and the apico-posterior subsegment of left upper lobe in 23.3% of lesions, then planning according to the site of the lesion in relation to the bronchial tree in the VB was done. Histopathological assessment was done with 61.5% neoplastic lesions and 38.5% inflammatory lesions.Conclusion
Multiplanar reconstruction images together with virtual bronchographic images were accurate in the detection of lesion’s site, depiction of degree of narrowing, and distal visualization of airways. This CT map should be used to guide bronchoscopy or to direct trans-bronchial needle biopsy to guarantee positive histopathological results. 相似文献8.

Objective
To investigate the therapeutic response of radiofrequency ablation for treatment of hepatocellular carcinoma and the consequence of portal hypertension on the survival final results.Patients & methods
168 patients with portal hypertension undergo radiofrequency ablation in the act of treatment of HCC (≤5?cm). Therapeutic response and prognostic outcomes were then analyzed. Overall survival was assessed using Kaplan-Meier method and multivariate analysis was achieved using the Cox regression model.Results
Primary and secondary complete ablation of HCC was obtained in 86.3% & 100% of patients respectively. Complication occurred in 13.6% of patients, and thrombocytopenia and prolonged prothrombin time were independent risk factors of complication. Overall survival after the follow-up period of about 25?months was 74.4%. Two elements based on multivariate analysis had been recognized as prognostic factors for poor survival: Thrombocytopenia (HR?=?1.008, P?=?.004), and left lobe location of the tumor (HR?=?0.392, P?≤?.03).Conclusion
This current study has shown that most cirrhotic patients with portal hypertension can tolerate RF ablation of HCC. The improved patient selection in terms of simple parameters such as platelet count, and prothrombin concentration, we will improve the outcome of RF ablation. 相似文献9.

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10.

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12.

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13.

Aim of the work
The aim of this study was to assess the utility of non-enhanced MRCP in reduction of biliary complications in LDLT donors and compare the results with IOC.Patients and methods
A total of 54 potential donors with preoperative MRCP (45 males, 9 females, age range 22–51 years). A total of 50 donors underwent right lobe resection and had IOC for comparison. The MRCP and IOC reports were reviewed.The MRCP was performed on 1.5 T MR magnets. Specificity, sensitivity and accuracy were analyzed and compared with IOC findings.Result
A total of 50 donors underwent MRCP and IOC.The findings were classified according to Yoshida et. al.’s study: 42.6% with type 1, 5.6% with type 2, 25.9% with type 3, 7.4% with type 4, and 18.5% with type 8. In comparison with MRCP findings with the golden standard IOC, the sensitivity, specificity and the diagnostic accuracy of MRCP were calculated:Sensitivity was of 88.2%), specificity was of 94.2% and accuracy was of 92%.Conclusion
Biliary complications remain common in LDLT. MRCP has potential in preoperative biliary evaluation for LDLT donors to minimize the postoperative biliary complications.Further improvements of MRCP in LDLT are required to increase its quality and accuracy. 相似文献14.

Aim of the work
To evaluate the role of fast imaging employing steady-state acquisition (FIESTA) together with conventional MRI and MR myelography (MRM) sequences in evaluation of brachial plexus traumatic roots injury in adults in correlation with surgical outcome.Subjects and methods
This prospective study included 20 patients (their mean age was 22.6?years). All patients came with initial clinical diagnosis of traumatic brachial plexus and positive electrodiagnostic tests. All underwent conventional MRI, FIESTA and MRM and the imaging findings were correlated with surgical outcome.Results
Combined evaluation of the conventional MRI, FIESTA and MRM sequences yielded highest diagnostic sensitivity (95%) of pseudomeningocele and non-visualized nerve root detection which are the most important marks of brachial plexus root injury compared to conventional MRI combined with FIESTA (90%) and to conventional MRI combined with myelography (85%)Conclusion
In traumatic brachial plexus root injury, it is vital to differentiate between pre- and postganglionic injuries. Combined conventional MRI/FIESTA/MRM depicted root injury has the highest sensitivity in detection of psuesdomeningiocele and non-visualized nerve root. 相似文献15.

Objective
To detect the diagnostic efficiency of sono elastographic strain ratio in discriminating malignant from benign solid breast masses and compare it with the sono elastographic elasticity score method.Patients and methods
This study included 120 histopathologically diagnosed solid breast masses from 120 females (mean age 38.2?years). Elastography score and strain ratio (SR) were performed for each mass. Receiver operating characteristic (ROC) curve was plotted for both methods.Results
The benign lesions had significant lower SR (mean 2.12?±?1.72) than that of malignant lesions (mean 6.91?±?3.96). The AUC from ROC curve was 0.98 for elasticity score and 0.99 for SR. The sensitivity, specificity, positive predictive value, negative predictive value and accuracy of the elasticity score in the diagnosis of solid breast masses were 100%, 88%, 83.3%, 100% and 92.5% respectively, and of the strain ratio were 93.3%, 97.3%, 95.5%, 96.1% and 95.8% respectively (when cutoff value 3.77 was used). There is no statistically significant difference found between both methods.Conclusion
SR has high diagnostic performance in differentiating malignant from benign solid breast masses, however there is no statistically significant difference between SR and elasticity score. 相似文献18.

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20.
