title: Intraosseous fat in 133Xe bone circulation measurements.
abstract: The amount of intraosseous fat in the proximal femur is exponentially dependent on a coefficient that has been formulated from the bone attenuation curve using 241Am bone mineral absorptiometry of the distal radius in the same subject. The coefficient enables estimation of the 133Xe partition coefficient between blood and nonhematopoietic tissues of bone. Bone circulation can then be measured in the proximal femur in diseases that affect the whole skeleton.
