title: Dual-energy X-ray absorptiometry in diagnosis of osteoporosis: basic principles, indications, and scan interpretation.
abstract: Dual-energy x-ray absorptiometry is currently the most commonly used modality for the diagnosis of osteoporosis, allowing fast, accurate, and noninvasive measurements of bone mineral density. In this review we discuss the principles, applications, advantages, and limitations of this diagnostic technique.
