Which is the method of choice for evaluating trabecular bone?

Question

Quizplus · Accepted Answer

Quantitative computed tomography (QCT) is the method of choice for evaluating trabecular bone. It allows for the separate measurement of cortical and trabecular bone density, which is important since trabecular bone is more metabolically active and sensitive to changes than cortical bone. QCT also provides information on bone geometry and microarchitecture. Dual-energy x-ray absorptiometry (DXA) is primarily used for measuring bone mineral density and is less accurate for evaluating trabecular bone. Quantitative ultrasound and dual-energy photon absorptiometry are not commonly used for trabecular bone evaluation.
