Abstract
Dual energy X-ray absorptiometry (DEXA) allows non-invasive direct measurement of bone mineral density. The aim of this study was to provide guidelines for the appropriate use of DEXA in our hospital in order to promote accurate diagnosis and timely, appropriate treatment. A multidisciplinary commission performed a systematic review of the relevant literature. Benefits, harms and costsEarly diagnosis through DEXA allows proper management of osteoporosis to minimize injury and disability, improve quality of life and reduce the personal and social costs associated with this condition. Potential harms include radiation exposure and cost. The harms and costs of the appropriate use of DEXA are minimal compared with those associated with osteoporosis. RecommendationsBone mineral density should be measured only to assist in making decisions on clinical management. DEXA is the best method of measuring bone density. Unless accelerated bone loss is suspected, DEXA should not be repeated within 2-year intervals to monitor therapy. The measurement and reporting of results should be standardized.
