摘要: Cardiac anatomy was defined by gated nuclear magnetic resonance (NMR) imaging at a field strength of 3.5 kGauss in eight normal subjects and 10 patients with chronic myocardial infarctions. Multisectional performed the spin-echo technique encompassed most left ventricle an time 5 to 12 min. In all internal cardiac structure well delineated without use any type contrast medium. The wall-blood interface sharply defined, resulting visualization trabeculations, papillary muscle, chordal structures both ventricles. ischemic heart disease, extent postinfarctional wall thinning, aneurysms, mural thrombi were depicted on NMR images. Images obtained second (delay = 56 msec) demonstrated high signal intensity regions ventricular chamber adjacent site aneurysms or infarctions; this finding suggested stasis blood region akinesis dyskinesis. results study show that is feasible as for human capable demonstrating variety abnormalities associated infarction. completely noninvasive clinical cardiovascular system.
