Study compares PET MPI, SPECT in detecting CAD

Intermountain Medical Center researchers found that PET myocardial perfusion imaging improved diagnosis rates for patients with severe obstructive coronary artery disease and reduced the occurrence of invasive catheterization without severe CAD identification, compared with SPECT scans. The findings, presented at the American College of Cardiology's annual meeting, also showed better identification of patients requiring revascularization, as well as reduced false positives and increased true positives in severe CAD diagnosis, with PET MPI.
