WebNov 6, 2014 · Myocardial CTP imaging can be performed on two ways. 2 Static CTP imaging is based on acquisition of an image of the myocardium during the approximate peak of the contrast bolus that enables qualitative evaluation of differences in enhancement between hypoperfused and normally perfused myocardium. WebMar 10, 2024 · The addition of CT perfusion (CTP) to standard coronary CT angiography is a reliable tool to improve diagnostic accuracy. CTP using static first-pass imaging enables qualitative assessment of the myocardial tissue, whereas dynamic perfusion imaging can also provide quantitative information on myocardial blood flow.
