Comparison of QCT and DXA: Osteoporosis Detection Rates in Postmenopausal Women

Figure 1

Images obtained from a 71.7-year-old woman whose bone mineral density was found to be normal on dual X-ray absorptiometry. (a) The T-scores for lumbar posteroanterior dual X-ray absorptiometry, the femoral neck, and the total hip were −0.1, −0.8, and −0.7, respectively. The trabecular bone mineral density of L2–L4 was 36.1 mg/cm³, and the diagnosis via lumbar quantitative computed tomography was osteoporosis. Sagittal lumbar spine images show two adjacent vertebral fractures with wedging, deformation of the end plates, and degenerative disc disease: (b) T₁ weighted and (c) T₂ weighted.
