Clinical Applications of Dynamic Computed Tomography

Abstract

Dynamic CT studies can be made for any organ or tissue in the body, in order to establish time-density relations which demonstrate the early phase of contrast enhancement in normal and pathologically altered tissues. First generation systems with scan times of more than 1 min per slice were capable of demonstrating the passage of contrast material in brain tumors over a considerable period of time. The first dynamic CT studies made with more modern CT systems were used to analyse regional blood circulation in the brain, since contrast media do not usually cross the blood-brain barrier into the interstitial space unless a brain lesion is present. Dynamic CT studies are used primarily for clarification of findings in the upper abdomen, where demonstration of differences in density permits better delineation of organic lesions and improved definition of alternatives in differential diagnosis.
