Noninvasive coronary angiography with multislice computed tomography and myocardial perfusion imaging

A total of 114 patients with an intermediate pretest likelihood of coronary artery disease were evaluated with both multislice computed tomography (MSCT) and myocardial perfusion imaging (MPI). Results showed that in the majority of cases, a normal MSCT scan was associated with normal perfusion. However, only half of patients with significant stenoses showed abnormal perfusion. Accordingly, MPI and MSCT are intrinsically different techniques and appear to be complementary rather than overlapping as they provide information on atherosclerosis versus ischemia, respectively.
