With the continuous development of CT technology, myocardial CT perfusion imaging (CTP) has exhibited great advantages and been shown to have incremental value over coronary CT angiography, providing functional evaluation of coronary artery disease (CAD). Comprehensive assessment of CAD using cardiac CT has become feasible. This article introduces the preliminary clinical experience and advances with CTP and briefly reviews the feasibility verification, diagnostic performance, clinical strategy optimization and prognostic evaluation of CTP.
