High resolution MRI of rat heart in age-related fibrosis, acute MI, and chronic MI. Novel approach to imaging fresh gadolinium-exposed tissue immediately post-mortem with retention of gadolinium distribution in the tissue. Correlation of microimaging cellular level areas of fibrosis to microscopy and histopathology. Fellows Pascale Beliveau, Sophia Hammer-Hansen. 2. Boehm, Manfred, NHLBI Protocol H-0184.Imaging Mouse vascular grafts. Fellow Dan Yang. 3. Boehm, Manfred, NHLBI Protocol H-0038R2.
