Comparison of QCT and DXA: Osteoporosis Detection Rates in Postmenopausal Women
Figure 2
Images obtained from a 59.5-year-old woman who was found by dual X-ray absorptiometry to have osteopenia. (a) The T-scores for lumbar posteroanterior dual X-ray absorptiometry, the femoral neck, and total hip were −1.6, −0.5, and −0.4, respectively. The trabecular bone mineral density of L2–L4 was 71.4 mg/cm3, indicating a potential diagnosis of osteoporosis according to the American College of Radiology guidelines. A lateral lumbar radiograph (b) and an axial computed tomography image (c) showed severe osteophytes and end plate sclerosis of the lumbar vertebrae. Focal sclerosis is apparent on the right accessory of L3.
