We reported, for the first time, MD and FA results obtained from femoral neck of healthy (H), osteopenic (OPE) and osteoporotic (OPO) subjects, classified according to DXA criteria. Because MD and FA in cancellous bone depend on both the trabecular-bone rearrangement and the marrow fat-water ratio content (FF) a DTI protocol in combination with 1H-MRS was used. Our preliminary results, show that MD/FF and FA/FF differentiate among H, OPE and OPO subjects with a high sensitivity and specificity in identifying H subjects. DTI-1H-MRS assessment in femoral neck might represent a potential procedure to improve the diagnostic confidence of osteoporosis.
