Excerpt
Use of non-invasive cardiac imaging is recommended in numerous clinical scenarios in order to provide diagnostic and prognostic information to guide clinical decision making.
1 Stress single-photon emission computed tomography (SPECT) myocardial perfusion imaging (MPI) is well validated and has proven value in identifying patients at high risk of a serious cardiac event, whereas a normal MPI study confers a benign prognosis with a low annual serious cardiac event rate of 0.6% per year.
2 However, there has always been concern that MPI can miss high-risk coronary artery disease (CAD) as in patients with balanced ischemia due to flow-limiting three-vessel CAD or left main stenosis,
