CRESCENT-II: Tiered cardiac CT protocol more efficient, faster than functional testing
December 13, 2017

A tiered cardiac CT protocol with dynamic perfusion imaging had similar effectiveness to functional testing in patients with suspected CAD, but took less time to process and resulted in fewer inappropriate invasive procedures, according to the CRESCENT-II trial.

Previous research has shown CT angiography can rule out CAD, but it was not known whether incorporating CT myocardial perfusion imaging as part of a tiered diagnostic approach would improve the clinical value and efficiency of cardiac CT in patients with angina, the researchers wrote in the study background.
