title: Intracoronary myocardial perfusion imaging: patterns in patients with coronary artery disease.
abstract: Myocardial imaging following the intracoronary injection of radiolabeled particles is used to identify transmural scars in patients being evaluated for coronary atherosclerosis. Selective imaging of the microcirculation derived from each major coronary vessel is accomplished using a dual radionuclide technique. This report illustrates the various normal and abnormal imaging patterns encountered in patients with coronary artery disease. The regional myocardial nomenclature proposed by the American Heart Association Council on Cardiovascular Surgery is used. Correlation of the nuclear study with the contrast arteriogram and ventriculogram is essential for identifying both transmural scars and regions of collateral circulation. The procedure is safe and can be performed during routine coronary angiography.
