Abstract

Using KAIS 0.15 Telsla resistive magnetic imaging system, ECG gated magnetic resonance (MR) image of variouscardiovascular disease was obtained in 10 patients. The findings of MR image of the cardiovascular disesase wereanlaysed and the results were as follows: 1. In 6 cases of acquired and congenital cardiac disease, there were 2cases of myocardial infarction, 1 case of mitral stenosis and 3 cases of corrected transpossition of greatvessels. The others were 3 cases of aortic disease and 1 case of pericardial effusion with lymphoma. 2. Myocardialthinning left ventricular aneurysm were detected in MR images of myocardial infarction. The left atrium was welldelineated and enlarged in the case of mitral stenosis. And segmental analysis was possible in the cases ofcorrected transposition since all cardiac structures were well delineated anatomically. 3. In aortic disease, thefindings of MR image were enlarged lumen, compressed cardic chambers in ascending aortic aneurysm, intimal flap,enhanced false lumen in dissecting aneurysm and irregular narrowing of aorta with arterial obstruction inTakayasu's arteritis. 4. Pericardial effusion revealed a conspicuous contrast with neighboring meidastinal fat andcardiac wall due to it low signal encircling cardiac wall. 5. ECG gated MR image is an accurate non-invasive imaging modality for the diagnosis of cardiovascular disease and better results of its clinical application areexpected in the futher development in the imaging system and more clinical experiences.
