Background; Multidetector computed tomographic (MDCT) angiography has become a key imaging investigation for assessment of the renal vasculature challenging conventional angiography.
Objective : assess the diagnostic performance and accuracy of multi-detector computed tomography angiography in evaluation of renal vascular abnormalities.
Subjects and Methods: Prospective study included 95 patients ( 60 mеn аnd 35 wоmеn) evaluated by MDCT renal аngiоgrаphy , divided into four groups . First group are renal donors prepared for renal transplant , Second group are patients with history of suspected renal trauma or post percutaneous nephrolithetomy hematuria , Third group are patients suspected for renovascular hypertension . Fourth group are patients with renal masses assesed for preoperative angio-embolization & surgical guidance . . MDCTA findings were correlated with conventional angiography or operative findings.
Results: MCT angiography results shows no significant statical deference compared with intraoperative findings in first group , as well as compared with conventional angiography regards detection of pseudoaneurysms in traumatic & post PCNL patients ( P VALUE > 0.05 ) in second group . In patients with suspected renovascular hypertension there was significant difference between renal artery doppler findings & MDCT angiography as well as conventional angiography ( P VALUE < 0.05 ) . MDCT Angiography has AUC of 0.973 ,Sensitivity 93.3% and Specificity 90% .
Conclusion: We can conclude that, MDCT Renal angiography is an excellent imaging investigation because it is a fast and non invasive tool that provides detailed evaluation of normal renal vascular anatomy, variants & abnormalities .
