Aim: Multi-Detector Computed tomography (MDCT) is one of the
best important modality in evaluation and management of primary
renovascular disease. Non enhanced CT is useful for demonstrating
renal hemorrhage, renal parenchymal or vascular calcifications, and
masses. Contrast material-enhanced CTAnd MDCT is essential to
identify global or regional nephrographic abnormalities resulting
from the vascular process (eg, renal infarcts, ischemia secondary to
renal artery stenosis, arteriovenous communications). In addition,
renal manifestations of a systemic disease (eg, vasculitis, thrombo-embolic
disease) can be seen at CT. In trauma, occlusion of the main renal
artery can be accurately diagnosed with contrast-enhanced CT. In
cases of spontaneous renal hemorrhage without an apparent cause (eg,
vasculitis, coagulopathy). Material & Methods: 100 patients of
different Reno vascular lesions are subjected to careful CT with
MDCT study performed to for more cases evaluation. Conclusion: MDCT
exclude renal cell carcinoma. The presence of fat in a hemorrhagic
renal mass larger than 4 cm in diameter is characteristic of
angiomyolipoma complicated by hemorrhage. Acute renal vein
thrombosis appears as a clot in a distended renal vein, whereas
renal vein retraction with collateral vessels is highly indicative
of chronic thrombosis. MDCT, especially following an intravenous
injection of iodinated contrast material, has greatly improved our
ability to directly image the proximal renal arteries and detect
vascular lesions.
