[Magnetic resonance tomography in diagnostics of coronary heart disease].

Contrast-enhanced magnetic resonance tomography (1.5 Tl) was used to examine 101 patients with coronary heart disease. It was shown that angina of effort was associated with disturbed myocardial perfusion manifest during the first passage of the contrast agent at sites with a hypointense signal. Patients with acute myocardial infarction exhibited, besides defective perfusion, hyperintense edematous regions on T2-weighted images as well as hyperintense sites of delayed contrast enhancement. The main symptoms of post-infarction cardiosclerosis in hyperintense zones of delayed contrast enhancement related to cicatrical lesions in myocardium. Disturbances of local contractility depending on the severity of ischemia and cicatrical lesions resulted in the impairment of overall left ventricular contractility.
