Renal Perfusion Studies by Means of CT

Conference paper


Sequential CT is a simple extension of conventional CT investigations for registering and evaluating the phenomena of contrast enhancement by repeating scans in the same sectional plane as quickly as possible after an intravenous bolus injection of contrast medium. Most of the presently used CT units have scan intervals of 10–15 s; the newest units have a higher scan rate intervals of 2–5 s. The parameter is the absorption value, which is directly observed and densitometrically detected by a software program and indicated in Hounsfield units (HU).
