Understanding DEXA Scans and Procedures

Rea, a radiologist technologist at MD Anderson, explains the DEXA scan, a test for assessing bone health and detecting osteoporosis. The scan measures bone density using low-dose X-rays, primarily in the hip and spine. The procedure is safe, painless, and requires no special preparation, though pregnant women and those who recently had certain radiologic tests should take precautions. During the scan, a mechanical arm passes over the body without contact, and the process takes about 20 minutes. Results are typically available within two days, and patients can resume normal activities immediately after the scan.
