Abstract

The purpose of this essay is a quick and comprehensive review of dual-energy x-ray absorptiometry in the diagnosis of osteoporosis that shows how to achieve the best performance in three steps. The three-step procedure for dual-energy x-ray absorptiometry includes image acquisition emphasizing proper patient positioning and regions of interest; analysis, including areas to scan and detection of artifacts that should be excluded from the analysis and noted in the report because they can necessitate additional imaging; and interpretation of results.
