Abstract
ä Opportunistic use of computed tomography (CT) allows assessment of bone status from studies obtained for other purposes. ä The linear x-ray attenuation coefficient is known as the Hounsfield unit (HU). ä HU values can be determined for any region of interest using standard imaging software. ä HU values strongly correlate with bone mineral density. ä A threshold of <135 HU for the L1 vertebral body indicates a risk for osteoporosis. ä HU values have been used to assess other bone regions, including the wrist, proximal and distal end of the femur, and sacrum, to predict future fracture and the presence of osteoporosis. ä Opportunistic use of CT aids in the identification of patients who are not otherwise suspected to be at risk for osteoporosis.
