| Popis: | Anorexia nervosa (AN) is classified as a high-risk factor for osteoporotic fractures. Dual X-ray absorptiometry (DXA) is the most popular method for measuring bone loss, but it is less sensitive than quantitative computed tomography (QCT). We compared DXA and QCT in measuring the lumbar spine of 17 female patients with AN and 27 healthy subjects. We found discordance between DXA and QCT using World Health Organization (WHO) criteria with the T-score. With QCT as a reference method because of its sensitivity, we found one false-negative, one false-positive, and two misdiagnosed cases. We suggest some correction factors to improve DXA evaluation and screening of bone loss in AN. |
