Purpose : To evaluate renal vasculature using a multidetector CT scanner (Multidetector CT Angiography). Materials & Methods : Twenty patients were evaluated using a multislice CT scanner (Siemens, Volume Zoom, Siemens Corp., Siemenstrasse, Forchheim, Germany), out of which twelve had complaints of hypertension, abdominal pain and eight were renal donors. The spiral CT acquisition was done by rapid intravenous injection of 100 cc of water-soluble iodinated contrast medium via a pressure injector at the rate of 2.5ml/sec via a 20G angiocath in the antecubital vein. Images of 1.25 mm slice thickness with 1mm slice collimation were taken from the twelfth dorsal or the first lumbar vertebral level upto the pubic symphysis. No oral contrast was given in these patients. Post processing of the reconstructed axial data was done using Maximum Intensity Projection {MIP}, Surface Shaded Display (SSD) and the Volume Rendering (VR) technique. Results : Out of the twenty subjects studied: six had renal artery stenosis (RAS), eight were donors, three had renal malignancies (RCC), one had an ectopic kidney and two were cases of aortoarteritis with renal involvement. Conclusion : CT angiography is a good, cost effective and non-invasive modality as it gives vascular, anatomic and functional depiction of the kidneys in one sitting
