ABSTRACT

Objective To study MRI manifestation of the non-diver bone infarction. Methods Six cases of non-diver bone infarction involved 18 bones totally, in which 15 bones were confirmed by surgical operation and pathology. All cases were examined by MRI through T 1WI, T 2WI, PDWI, FLASH T 2WI, and by X-ray plain film. Result (1) Major MRI manifestation was moderate signal intensity on T 1WI and inhomogenous high signal intensity on T 2WI in the centers of the foci whose margin were rugged and rough bands which were low signal intensity on T 1WI and two layers on T 2WI. (2) MRI manifestation was atypical when focus was small (
