Abstract

Noninvasive cardiac imaging has evolved substantially over the past few years. New reconstruction algorithms and a new generation of y-cameras with cadmiumzinc telluride (CZT) semiconductor detectors have shortened scan time and improved image quality in myocardial perfusion imaging (MPI) by single photon emission computed tomography (SPECT). In addition, technical refinements in coronary computed tomography angiography (CCTA) have led to a substantial dose reduction while image quality has improved. However, invasive coronary angiography has remained the anatomic standard of reference even though it is associated with a nonnegligible perioperative morbidity and mortality that suggests confining its use to patients who will benefit from a subsequent revascularization procedure. The poor agreement between the severity of coronary artery stenosis (morphological assessment) and the hemodynamical relevance of the stenosis (functional assessment) has been shown; thus, the coronary anatomy rarely allows estimation of the patho-physiologic relevance of a coronary lesion.
