Bone Abstracts

Bone marrow lesions (BMLs), previously denoted bone marrow edema are detected as water signals on MR scans (low intensity on T1 weighted images and high intensity on T2 weighted scans). Previous histologic studies were unable to demonstrate any edematous changes at the tissue level, which led us to hypothesize that the water signal stems from increased vascularization accompanying a high turnover state in bone. To test this hypothesis we performed tetracy...
