Refers to two types of bone density tests: dual-energy x-ray absorptiometry (DEXA) scan, and quantitative computerized topography (QCT) which determines the degree of bone mineralization.
Tissue in the central cavity of long bones that functions to store fat or produce red blood cells.
A radiographic technique used to measure the density of bone, to assess bone structure and strength, and to diagnose such conditions as osteoporosis.
A method of determining the density of bone by use of radiographic techniques. The use of dual photon absorptiometry provides density data of the axial skeleton with a precision of 97% to 98%. It is used in testing for degree of osteoporosis.
