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2.

Objective
Assessing the role of MSCT compared to TTE in pediatric patients with congenital heart diseases especially the thoracic congenital vascular anomalies.Methods
54 pediatric patients underwent a 128 detectors computed tomography cardiac angiography with retrospective ECG-gating. Images were reviewed based on segmental approach using the operative data (35/54 patients) or cardiac catheterization (19/54 patients) findings as reference standard. Sensitivity, specificity, positive and negative predictive values and accuracy of TTE and MDCT were evaluated.Results
MDCT was superior to TTE in evaluating vascular lesions (aortic, conotruncal, coronary artery, major aorto-pulmonary collaterals, patent ductus arteriosus, venous anomalies and postoperative complications) as well as pulmonary lesions; while TTE was superior in intracardiac anomalies with equal performance in (pulmonary artery anomalies, concordance and valvular atresia). MDCT achieved (100%, 96.3% and 87%) accuracies compared to TTE (94.4%, 85.2% & 96.3%) for delineating isolated vascular anomalies, complex vascular anomalies and intracardiac anomalies respectively.Conclusion
The main added value of cardiac MDCT to TTE is the precise illustration of the extracardiac anatomic structures, without adding significant information on intracardiac abnormalities. Using MDCT with TTE has improved the diagnostic accuracy thus obviating the need for diagnostic cardiac catheterization especially in critically ill patients. 相似文献3.

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7.

Objective
We evaluated multidetector computed tomography (MDCT) accuracy for the prediction of the optimal prosthetic aortic valve deployment angle in trans-catheter aortic valve implantation (TAVI) with the different variables.Methods
Sixty-six patients underwent contrast-enhanced MDCT before TAVI. From the three-dimensional aortic root reconstructions, we get the appropriate perpendicular aortic valve projection at which the bases of the aortic valve cusps were on a straight line. The predicted angles by MDCT were compared to the perpendicular fluoroscopic angles of the prosthetic valve. The degree of MDCT accuracy was defined as accurate, suitable or inaccurate according to the difference between the predicted angles and the perpendicular prosthetic valve projections. The degree of aortic cusp calcification, annular ellipticity, the type of aortic valve (to be tricuspid or bicuspid), were compared in patients with accurate, suitable and inaccurate prediction. The radiation exposure and volume of the used contrast agent were also considered in the comparison.Results
MDCT prediction was accurate in 84.8% of cases, suitable in 9.1% and inaccurate in 6.1% of cases. There was a significant association between MDCT accuracy and the valve type with higher rates of accurate prediction with tricuspid aortic valves than bicuspid valves (93.1% versus 25%, respectively). The mean number of aortograms and the volume of contrast agent used for TAVI procedure were significantly less in patients with accurate CT prediction (p < 0.001).Conclusion
MDCT allows accurate prediction of the proper deployment angle for TAVI. Bicuspid aortic valve is significantly associated with fewer rates of accurate prediction. 相似文献8.

Purpose
To evaluate the role of non-contrast multidetector CT (MDCT) reliability in localizing CSF leaks and skull base defects in correlation to operative findings.Materials and methods
Twenty patients clinically diagnosed to have CSF rhinorrhea; 8 spontaneous and 12 post-traumatic patients were evaluated using 64-rows MDCT with slice section 0.6 mm. CT is considered accurate if correctly determine the site and size of bony defect as matched with operative findings.Results
MDCT accurately detected the site of presumed CSF leak in 19 out of 20 cases with sensitivity 95%. Cribriform plate defect is the most common site of defect in 40% of cases with 75% of cases categorized as Keros type II. The consensus image with fair agreement (K = 0.38) shows that coronal reformat has the highest diagnostic performance in 75% of cases while the least diagnostic value is encountered with the axial plane in 15% of cases (p = 0.095). There is almost a perfect agreement (K = 0.810) between the MDCT measurements and operative size of bony defect with minimal difference in 10% of patients (P < 0.001).Conclusion
Non-contrast MDCT is an accurate reliable non-invasive imaging modality for preoperative evaluation of CSF rhinorrhea. 相似文献9.

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11.

Purpose
To assess the role of dynamic contrast- enhanced and diffusion-weighted (DWI) MRI in the evaluation of the response of hepatocellular carcinoma (HCC) after chemoembolization.Patient & method
30 patients having 40 HCC lesions underwent transcatheter arterial chemoembolization (TACE). Ages ranged between 41 and 76?years. All examinations were performed using Philips 1.5 Tesla MRI (Achieva). Precontrast T1, T2, Dynamic contrast enhanced and respiratory triggered DWI MR images with (b?=?50, 400, 800?mm/s). DWI MRI images and Contrast-enhanced MRI images after TACE are assessed to evaluate post treatment response. DWI was used to create ADC maps and ADC values were calculated looking for a cut off value using the ROC curve.Results
Dynamic MRI had a sensitivity of 94.1%, a specificity of 95.6%, PPV value of 94.1%, NPV of 95.6% and an overall agreement of 95% compared to 82%, 73.9%, 70%, 85% and 77.5% respectively of DWI MRI. The difference between the malignant residual and well ablated groups' ADC variables was statistically significant P value 0.009.Conclusion
Dynamic and diffusion MRI complete each other in assessment of HCC response to therapy, especially in those who cannot properly hold their breath that cause degradation of the dynamic MR quality. 相似文献13.

Purpose
The study aims to compare the accuracy of washout and perfusion CT techniques in diagnosis of adrenal tumors.Patients and methods
A prospective study included 38 patients with incidentally detected adrenal masses on conventional abdominal CT studies performed for unrelated reasons were subjected to full medical history, physical examinations, serum creatinine assessment, dynamic perfusion CT using 64 MDCT scanner with Absolute washout (APW), Relative washout (RPW) assessment and CT perfusion parameters calculation [perfusion, Peak enhancement intensity (PEI), Time to peak (TTP) & Blood volume (BV)]. Time density curves (TDCs) for all adrenal masses were done. The gold standard was either follow up or histopathological examination after fine needle biopsy or surgical resection.Results
Washout CT differentiated between adenomas and non-adenomas using APW (≥55%) with sensitivity 73.3%, specificity 90% and accuracy 82.8%, and using RPW (≥36%) with sensitivity 53.3%, specificity 85% and accuracy 81.8%. Perfusion CT differentiated between adenomas and nonadenomas using BV (≥15 ml/100 g) with sensitivity 80%, specificity 75% and accuracy 77.1%. TDC curves of adenomas show slow-rise platform pattern.Conclusion
Perfusion CT can distinguish between adrenal adenomas and non-adenomas using the BV, however washout CT was more accurate than perfusion CT in characterization of adrenal masses using the APW and RPW. 相似文献15.

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17.

Purpose
The aim of this study was to highlight the different computed tomography (CT) features of groove pancreatitis (GP) in order to make this entity more familiar to radiologist.Patients & method
This study enrolled 15 patients who had histopathologically confirmed GP. Their CT scans were retrospectively reviewed for the encountered manifestations.Results
Pure & segmental forms were identified retrospectively in 6 & 9 patients. The most frequent findings noted in patients' scans were the following, in descending order: medial duodenal wall thickening & cysts, duodenal luminal narrowing, regional lymphadenopathies, pancreatic involvement, isolated groove affection, pancreatic calcifications, distal CBD narrowing, pancreatic duct abnormalities, and retro-peritoneal stranding.Conclusion
Although the CT features of GP mimic other peripancreatic tumors, yet the constantly associated findings in the proven cases of GP in our study were: duodenal wall thickening, cysts formation, and luminal narrowing. So the presence of these features in alcoholic middle aged male patient with groove or pancreatic lesion, have to trigger radiologist's dubiety of GP entity and so to be addressed in his opinion. Nevertheless, GP diagnosis is still challenging & should be considered based on clinical & radiological data in conjunction with the laboratory and pathological results. 相似文献18.

Objective
To evaluate the use of diffusion tensor imaging (DTI) and fractional anisotropy (FA) as prognostic tools in anticipating the recovery of stroke patients.Patients and methods
40 patients were included in our study after exclusion of 23 patients. All patients admitted in Neurology Department with stroke. The patients subjected to National Institute of Health Stroke Scale (NIHSS) followed by MRI with DTI and FA calculation. Follow up after three months was done based on the Modified Rankin Score (MRS). The results were compared and statistically analyzed.Results
There was a statistical significant between the NIHSS and DTI pattern at the time of admission (p value?<?0.05) reflecting the severity of the stroke with 22 patients showed disrupted fibers (55%), of which 16 patients were categorized as moderate NIHSS and 19 patients showed poor outcome. Relative FA equal 0.8 was found to be the cut off value in predicting the poor or good prognosis using MRS as a reference with 94.4% sensitivity, 90.9% specificity and 0.833 area under curve.Conclusion
DTI is a prognostic tool in anticipating the recovery of the stroke patients. Moreover, the relative FA score works as more additive value in evaluation of the patient improvement. 相似文献19.
