Purpose
We aimed to assess potential role of strain sonoelastography in diagnosing focal testicular lesions.Patient & methods
21 patients with 23 focal testicular lesions were subjected to sonoelastography. Compression was performed manually by the transducer upon the testis and monitored on the compression graph on the machine. Diagnosis was reached either by surgical resection, or follow-up.Result
23 focal testicular lesions were included. 10 lesions were in the right and 9 in the left, and 2 lesions are bilateral. Cases included 7 focal orchitis (30.5%), two hematomas (8.7%), 7 scar tissue (30.5%), 4 seminomas (17.4%), one choriocrcinoma (4.3%), one epidermoid cyst (4.3%), and one hydatid cyst (4.3%). On strain Sonoelastography; all four seminomas and 7 scars were of low strain, also the epidermoid cyst and the two hematomas were hard, while the 7 cases of focal orchitis showed high strain. The cases of choriocarcinoma and the hydatid cyst showed mixed strain patterns. Statistical analyses showed a sensitivity of 100% in identifying neoplastic lesions, with a specificity of 40%, a negative predictive value of 100%, and a positive predictive value of 37.5%.Conclusion
Strain Sonoelastography is useful adjunct method to differentiate benign from malignant focal testicular lesions. 相似文献2.

Background
Characterization of tendo-ligamentous pathologies of wrist remains problematic, despite advances in imaging. By using clinical history and imaging appearance, one can determine the diagnosis. USG is used as first imaging modality whereas MRI aids in making a specific diagnosis of few of the lesions.Aims
To investigate the etiological spectrum of tendo-ligamentous pathologies of wrist on USG & MRI with statistical correlation.Patients and methods
80 patients (male/female = 46/34) with complaint of swelling or pain in wrist were included and underwent USG and MRI of both the wrists.Results
The spectrum included ganglion cysts, vascular malformations, tenosynovitis, tendinopathy, ligament tears and fibrosis. The analysis was done using kappa coefficient and spearman's rho correlation coefficient. The strength of agreement between USG and MRI for the diagnosis of ganglion cysts, vascular malformations, tenosynovitis and tendinopathy was found to be very good.Conclusion
USG provides detailed depiction of superficial structures, is less expensive, and allows dynamic examinations of the wrist. It should be the first choice of investigation for majority of the cystic, tendinous, vascular, and fibrotic pathologies of the wrist. However, less promising results were observed for ligamentous pathologies on USG in our study. 相似文献3.

Objective
The aim of this study was to assess the ability of CT to predict the pathological nature of pancreatic cystic lesions if it is benign, malignant or premalignant.Methods
This is a retrospective study from the database of our hospital EMR (electronic medical records) for pancreatic lesions from patients who proven to be of pathological cystic nature. The diagnosis and characterization of pancreatic cysts were done by multislice 32 CT examination. We reviewed the data from the radiology, surgery and pathology departments from the period of November 2012 until January 2015. We compared between operative and pathological data and findings of MDCT using chi square test.Results
We reviewed the data from the radiology, surgery and pathology departments from the period of November 2012 until January 2015. The study was done on 66 patients. Our results showed that CT features for benign cystic lesions are lobulated shape and a thin wall (≤1?mm) while the round or oval shape or a complex cystic shape with tubular cyst and a thick wall (>1?mm) are more frequently seen in pancreatic premalignant and malignant macrocytic lesions.Conclusion
CT with thin section images allows adequate morphological characterization of macrocytic pancreatic masses that could predict its pathological nature if benign or malignant. 相似文献5.

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7.

Purpose
Evaluate role of MRI and TRICKS-MR angiography in diagnosis of facial vascular anomalies.Material and methods
This study included 22 patients (mean age 9?years) with proved facial vascular anomalies on basis of interventional/surgical procedures (n?=?19) or clinical follow up (n?=?3). They underwent MRI examination with TRICKS-MRA. Images were evaluated for lesion location, size, feeding arteries and draining veins.Results
AVM was diagnosed in 15 patients (68.2%), hemangioma (5) patients (27.7%) and low flow venous malformation (2) patients (9.1%). TRICKS-MRA was accurate in diagnosis of 25 feeding arteries out of total 27 included in the study with 92.6% positive predictive value, 100% negative predictive value and 93.1% accuracy. AVMs were treated with sclerotherapy (26.7%), embolization (40%) and combined embolization and surgery (33.3%). Surgery was done in 2 hemangiomas (40%) while the other three patients (60%) underwent clinical follow up for 2?years with stationary course. The 2 patients with venous malformation underwent successful sclerotherapy.Conclusion
MRI & TRICKS-MRA provide excellent diagnostic data for assessment of facial vascular anomalies. TRICKS -MRA adds precise delineation of the vascular mapping, regarding feeding arteries and draining veins which helps in planning of therapeutic approach and reduces needing for invasive DSA. 相似文献8.

Objective
To assess the role of multislice computed tomography (MSCT) in the diagnosis of mesenteric vascular occlusion.Patients and methods
This study was performed on 30 patients clinically suspected and radiologically confirmed to have mesenteric vascular occlusion, they were examined with 64 row MSCT and were evaluated for evidence of bowel wall changes and abnormal mesenteric vascular changes.Results
We found that the most prevalent MSCT findings were bowel wall thickening followed by diminished wall enhancement. MSCT gave an accurate diagnosis of the cause of mesenteric vascular occlusion as proved by the final diagnosis based on surgical exploration, laboratory investigations and clinical follow-up.Conclusion
MSCT is accurate, fast and non invasive technique which should be used in clinically suspected patients with MVO in order to confirm the diagnosis, identify the aetiology and in addition assessing the bowel loop status for adequate management with good prognosis. 相似文献16.

Aim of work
To assess the role of color Doppler ultrasonography and multidetector computed tomography angiography (MDCTA) in diagnosis of uterine arteriovenous malformations (AVMs).Methodology
Twenty patients were referred to the radiodiagnosis and imaging department, faculty of medicine, Tanta University from obstetric and gynecology department. All patients were suspected clinically to have uterine arteriovenous malformations. All were subjected to history taking regarding clinical state, laboratory investigation and color Doppler ultrasonography and multidetector computed tomography angiography of the pelvis.Results
Color Doppler ultrasound sensitivity was 100% in detecting a uterine hypervascular lesion and highly suggesting the diagnosis of uterine AVM and the sensitivity of MDCT angiography was 100% in diagnosing and evaluating uterine AVM.Conclusion
Doppler US can strongly suggest the presence of AVM but patient should undergo CT angiography for definitive diagnosis and possible embolization, as CTA helps in providing valuable cross sectional anatomical details about the lesion, its extent and its surroundings. 相似文献18.

Purpose
to evaluate the role of three dimentional power doppler ultrasonography (3D PDUS) of the uteroplacental circulation in early pregnancy as a screening tool for prediction of preeclampsia.Patients and methods
50 pregnant women who came to do routine ultrasound scan between 11 and 13.6?weeks of pregnancy during the period from February 2016 to April 2016. Placental volume and vascularization indices were obtained, and vascular index (VI), flow index (FI), blood vessels and blood flow index (VFI) were calculated by three-dimensional Doppler histogram.Results
Of the included 50 pregnant women, 22% developed preeclampsia and 78% did not develop preeclampsia. The placental blood flow perfusion in patients with pre-eclampsia had a lower VI, FI and VFI compared to non preeclamptic women with highly significant statistical difference (P?<?0.001)Conclusion
3D PDUS can be used as an effective screening tool to predict preeclampsia in early pregnancy. 相似文献19.

Objectives
To evaluate accuracy of computed tomography angiography (CTA) in evaluation of post traumatic renal vascular injury.Patients and methods
38 patients were presented with post traumatic intermittent or persistent hematuria. Renal CTA and digital subtraction angiography (DSA) were done for all patients.Results
CTA demonstrated pseudoaneurysm (PA) in 30 patients (78.9%) and no vascular lesions in 8 patient (21.1%). CTA had 86.11% sensitivity and 50% specificity in detection of post traumatic renal pseudoaneurysms, CTA missed diagnosis of renal arteriovenous fistula (RAVF) in 10 patients which discovered later by DSA.Conclusion
CTA with MIP as non invasive technique widely replaced renal DSA in detection of posttraumatic renal pseudoaneurysm. Renal DSA is still best modality in detection of RAVF and also has the upper hand in planning of selective renal artery embolization for the management of persistent or delayed hemorrhage from renal vessels. 相似文献20.
