ABSTRACT
The coronal sectional image of computerized tomography creates an image that is similar to an excretory urogram. It also provides more clearly delineated renal image and image of adjacent organs than an excretory urogram. Further more, the number, extent, and content of renal mats lesions used to discriminate density difference can be determined with relatively great accuracy. This image of computerized tomography is useful to understand and make a diagnosis of renal disease. Coronal sectional image of computerized tomography is more informative in evaluation of retroperitoneum space than conventional radiography. Recently we observed several cases of renal disease-renal cell ca, simple renal cyst, angiomyolipoma, retroperitoneal teratoma, pheochromocytoma, hydronephrosis which could be detected with coronal sectional image of computerized tomography.
