Cine-MR Imaging was done in 2 normal persons and 9 patients of valvular heart disease with 2.0Tsuperconducting MR system(Spectro-20000; GoldStar, Korea). The MRI was undertaken using gradient echo technique with small flip angle. Repetition time (TR) was 34 msec, and echo time (TE), 18 msec. In most cases, 20 to 30frames could be obtained during one cardiac cycle, With normal heart, high signal intensity was identified in theblood filled cardiac chambers. Transient signal void was observed near tricuspid, mitral and aortic valves due tothe tubulences induced by valve opening or closure, In 6 cases of mitral valvular disease, mitral valve wasidentified in all cases. The valvular motion was limited revealing doming toward cardiac apex during diastole.Signal void was evident in pansystolic phase of left ventricle in all cases. evidences of combined aortic ortricuspid valve disease were also demonstrated, revealing signal void in the corresponding cardiac chambers.Cine-MRI seemed to be not only a good non-invasive diagnostic modality for the valvular heart disease, but also anaccurate modality for cardiac functional evaluation.
