PRESENT STATUS AND PERSPECTIVE OF MAGNETIC RESONANCE IMAGING IN SURGERY
－ANALYSIS OF CARDIOVASCULAR DISEASE－
Brief review was presented concerning principle, present status and perspective of magnetic resonance imaging (MRI). Magnetic resonance image has a high spatial resolution and gives functional and chemical information without any invasion. In this study, MRI was shown to be useful in three dimensional analysis of cardiovascular disease, such as myocardial infarction, hypertrophic cardiomyopathy, valvular and congenital heart disease. ECG-gated image allowed wall motion analysis and volume study of the left ventricle. In addition, animal experiments showed MRI to be capable of detection of early stage of myocardial rejection after heart transplantation based on elongation of T-2 parameter. Furthermore, MRI was a method of choice in diagnosis of disease of the aorta. For instance, in patients with aortic dissection, intimal flap was demonstrated to separate the true and false lumen. MRI was also able to distinguish the true and false lumens by the difference of the blood flow velocity. The tear of the intima could be seen in some cases. Cine MRI, which was recently developed, would extend the application of MRI in the future, because it gives precise anatomical and functional information with excellent temporal resolution, comparative with the other diagnostic imaging.
