Abstract

A combinationof high gradient (0.46mT/cm) and small radiofrequency coils (8cm diameter) was used to obtaneimages with effective thickness of 2.0mm and pixel dimensions as small as 196 micron in the live chick embryo andsurgically resected human femoral head with avascular necrosis. The signal-to noise ratio was sufficient to allowidentification of major anatomical structures of live chick embryo and delineation of osteonecrotic segment infemoral head. The changes of signal intensity in necrotic femoral head was well correlated with histopathologicfindings. MR microscopy is considered as a good research modality in the field of embryology, teratology and MRcharacterization.
