It
would be useful to have a reliable means of predicting bone loss. As reduced
bone perfusion and increased marrow fat content are associated with
osteoporosis, this longitudinal study was undertaken to determine how well MR
perfusion indices and marrow fat content at baseline could predict bone loss.
It showed that reduced bone perfusion indices or increased marrow fat content
at baseline is associated with increased bone loss over the ensuring four
years with a predictive capacity comparable to traditional risk factors.
MR-based indices also reliably distinguished future fast from slow bone
losers. MRI has potential in predicting bone loss.
