Pharmacologic Stress CT myocardial perfusion imaging

Although coronary angiography and calcium scoring are widely accepted methods in evaluating patients with coronary artery disease, the use of stress CT myocardial perfusion imaging is currently limited. It allows assessment of myocardial perfusion at rest and during pharmacologic vasodilation as well as estimation of fractional flow reserve.

New methods combining coronary CT angiography with either vasodilator stress perfusion imaging or computational fractional flow reserve (FFR) measurements may offer combined anatomic and physiologic CT assessment.
