The latter use is facilitated by the well-documented relationship between the extent and severity of stress-induced myocardial perfusion abnormalities and the risk for subsequent adverse cardiac events. Despite these utilities, stress/rest MPI imaging has an important limitation: while myocardial perfusion abnormalities are useful for assessing the hemodynamic significance of obstructive coronary stenosis, many patients with normal stress/rest MPI studies have a substantial magnitude of subclinical coronary atherosclerosis, which cannot be detected because they are not flow-limiting in magnitude.1,2 Coronary artery calcium (CAC) scanning is a complementary test that can detect subclinical atherosclerosis.
