Abstract

Measurements have been made in the rat femur in vivo and ex vivo by using an asymmetric spin echo technique of T~2β€²~, the susceptibility contribution to T~2~*. The trabecular spacing in this study in rat bone is considerably less than in previous studies in the human. A significant increase in T~2β€²~ was seen in vivo 3 mm proximal to the growth plate with ovariectomy (a model of osteopenia), from 8.1 Β± 0.7 to 10.0 Β± 0.6 ms. Parallel changes in trabecular bone mineral density measured by quantitative computed tomography were found. T~2β€²~ was higher in living bones than in the same bones measured post mortem.
