Bone densitometry, also known as a DEXA scan, is a simple imaging procedure used to measure bone mineral density. It helps detect conditions like osteoporosis and assess fracture risk. During the scan, the patient lies flat on a padded table while a low-dose X-ray beam passes over the spine, hip, or other bones. The procedure is non-invasive, painless, and usually completed within 10–15 minutes, providing valuable information about bone health.
