Answer

Although measurement of BMD at any site can be used to assess overall fracture risk, measurement at a particular site is the best predictor of fracture risk at that site. Whenever possible, the same technologist should perform subsequent measurements on the same patient using the same machine. This method can be used in both adults and children. Factors that may result in a falsely high BMD determination include spinal fractures, osteophytosis, scoliosis, and extraspinal (eg, aortic) calcification.
