MR imaging of ischemic heart disease.

When ischemic heart disease (IHD) is suspected or confirmed, the primary imaging modality is echocardiography. When appropriate, complementary examinations can be performed. These include stress perfusion scintigraphy, cardiac catheterization, coronary angiography, and CT. MR imaging techniques have developed rapidly over the past several years, and MR imaging has the ability to delineate myocardial perfusion, ventricular function, and myocardial viability in a single examination. Although coronary MR angiography is promising, in recent years it has been supplanted as a noninvasive imaging modality by coronary CT angiography. The other capabilities of MR imaging suggest that it will be performed more and more frequently for the assessment of IHD.
