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2.

Objective
A comparative study of manual and automated post processing software tools to measure CT parameters before Transcatheter Aortic Valve Implantation (TAVI).Patients and methods
51 patients were included; all admitted to the Cardiology Department with clinically established severe aortic stenosis, in whom TAVI was the treatment of choice. All patients underwent CT angiography (CTA) pre-TAVI. The CT images were post processed and the needed CT parameters were calculated using both manual and automated methods. The results were compared for statistical analysis.Results
Only 43 patients completed the study, with mean age 65?years old. The automated software provided accurate almost similar results as the manual method, especially for aortic annulus area and aortic circumference measurements (p-value?=?1 and 0.548) and was accepted for left and right coronary artery ostium height (p-value?=?0.191 and 0.635).However, there was a statistically significant difference for the minor diameter axis and mean annular diameter (p-value?=?0.001 and 0.021).Conclusion
The automated software introduced rapid, accurate and reliable measurements for the aortic annulus in cases prepared for TAVI and can be used as a standard method. Also, it can be performed by junior staff with avoidable human errors. 相似文献3.

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4.

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7.

Aim
To compare 3D steady-state free-precession (SSFP) non-contrast magnetic resonance angiography (NC-MRA) with contrast-enhanced MRA (CE-MRA) for quantitative and qualitative analysis of thoracic arteries in pediatric patients with congenital heart disease.Methodology
Forty patients with thoracic vascular anomalies (22 boys & 18 girls) ranging in age between 6?months and 14?years (mean age 4.58?±?4.5) were included in this prospective study. Measurements of the thoracic arteries were taken by 3D SSFP NC-MRA & CE-MRA. Image quality was assessed using a four-point score. Pearson's and Spearman's Correlation Coefficients were calculated for correlation analysis while Student's t and Mann-Whitney U tests were used for comparative analysis, Bland-Altman plots were employed to demonstrate the level of agreement between the 2 techniques.Results
Measurements from NC-CMRA images were comparable to those from CE-MRA. All measures highly correlated (r?>?0.9), 3D SSFP NC-MRA exhibited a significantly higher image quality score than contrast- enhanced MRA, the mean difference was significantly lower than that of the 3D SSFP; (p-value <0.0001).Conclusion
NC-MRA produced similar and comparable measurements of the thoracic arteries with superior image quality when compared to contrast- enhanced MRA in pediatric congenital heart defects. 相似文献8.

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10.

Objectives
To assess the role of 320 MDCT angiography in the evaluation of extra cardiac, vascular anomalies of great arteries and compare its results with transthoracic echocardiography and its impact on treatment planning.Materials and methods
This study included 39 patients, their age ranged from 16?days to 13?years. All of these patients underwent echocardiography and CTA examination using 320-MDCT. The images were analyzed using reconstruction techniques including MPR, cMPR, MinIP and VR techniques, the results were compared with surgical/catheter angiographic data.Results
MDCT was superior to echocardiography in diagnosis of great arteries anomalies (aortic and pulmonary). We found excellent agreement between 320-MDCT and surgery/catheter angiography with k?=?1.000 sensitivity, specificity, PPV, NPV, accuracy for aortic anomalies were 100%, 100%, 100%, 100%, 100% and 82.05%, 100%, 100%, 56.25% and 85.42% for MDCT and echocardiography respectively, and that of pulmonary anomalies were 100%, 100%, 100%, 100%, 100% and 84.62%, 100%, 100%, 92.86% and 94.87% for MDCT and echocardiography respectively.Conclusion
The main advantage added by 320-MDCT to transthoracic echocardiograpy was excellent delineation of the great arteries anomalies with suitable operative/catheteric decision without the need for the invasive diagnostic catheter angiography to the patients. 相似文献12.

Aim
Assessment of the clinical benefit of [18F]-FDG PET/CT examinations in restaging of patients with non Hodgkin lymphoma (NHL) in Egypt.Patients, methods
This study was performed on 45 patients with NHL. PET-CT and CECT were analyzed after end of chemotherapy regimen, using 12?months follow-up as standard of reference.Results
Follow-up of patients with NHL after 12?months of treatment revealed significant differences between staging by CT versus PET/CT (P?=?0.0001). Disease was upstaged by PET/CT in 36% (mostly in stages I and II) and downstaged in only 2% of patients. Agreement between PET-CT & CECT were usually in stage III and IV. Evaluation showed a sensitivity of 77% for CT alone, 95% for FDG-PET-CT.Conclusion
FDG PET-CT significantly improved sensitivity and specificity in restaging of NHL and therefore should be used routinely in follow up of patients with lymphoma. 相似文献13.

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15.

Background and objective
Laparoscopic sleeve gastrectomy become widely employed and accepted operation in between Arab population as a permanent solution for morbid obesity. There are many acute complications associated with LSG such postoperative leaks or bleeding, abscess formation, splenic infarction and portal vein thrombosis. The purpose of the study is to present how multidetector CT is beneficial as a screening investigation to detect these complications.Methods
We retrospectively review CT images done in the first week post operative for280 patients subjected to LSG the center in the period between July 2017-December 2017 (average age 39.5?years old).Results
the leak was suspected in 3 patients documented by a direct leak of contrast in one of them, 2 patients active bleeding was clinically suspected, but the exact site of bleeding could not be identified by CT, 15 patients had serous fluid collection, splenic infarction was noticed in 18 patients, 3 patients developed postoperative hematoma one of them become infected, anterior abdominal wall hematoma seen in 5 patients, one patient developed portal vein thrombosis.Conclusion
CT is an important imaging tool to diagnose post LSG complications. 相似文献19.

Objective
To evaluate the outcome and the cost value of surgical clips use as guidance for breast cancer localization in patients prepared for neoadjuvant chemotherapy (NAC).Methods
A prospective study of 43 patients confirmed histopathologically to have breast cancer and prepared to receive pre-operative NAC. Surgical clips were inserted via US guidance. The patients were followed up by mammography and US before surgery to evaluate the treatment response meanwhile, assessment of clips location, migration and complications. The overall cost of clips was also calculated.Results
Only 32 patients completed the study; the mean time interval was 32?weeks?±?2?weeks between the clip insertion date and the surgery. The number of the inserted clips was 34 surgical clips. Only two cases showed positive migration yet with no evidence of other complications occurred in our study patients. The average cost of the surgical clips was 145?±?20 Egyptian pounds (average 8–9 US$).Conclusion
Surgical clips can be used safely to replace the usual commercial markers in the localization of breast cancer before NAC. They showed effective results with no complications, don't interfere with the patients' imaging and of the significant low cost compared to the commercial ones. 相似文献20.
