What should you know about DEXA scan analysis?

A DEXA report commonly describes bone mineral density at the hip and lower spine, although other areas may be measured. The result may include a T-score for comparison with the average bone density of a healthy young adult and a Z-score for comparison with people of a similar age and sex. These figures help a clinician describe bone density, but they are not a diagnosis considered in isolation. Age, previous fractures, medicines, menopause status, other illnesses, and the quality of the scan all affect interpretation.

A lower density can make bones less resistant to everyday forces, while a stable result over time can help show how a treatment or health change is affecting bone. Comparing scans is most useful when performed on suitable equipment and interpreted alongside the earlier report.

Read the measured sites, scores, comparison with an earlier scan, and the report's conclusion together. Arrange a review with the clinician who requested the test, especially if the report mentions low bone density, a vertebral fracture, or a need for further assessment. Share a list of medicines and supplements, your fracture history, falls, smoking or alcohol habits, and any condition that may affect bone health. Your clinician may discuss resistance exercise, safe balance work, calcium and vitamin D intake, fall prevention, or treatment options suited to your health.

Seek prompt medical care after a significant fall or injury if you have severe back, hip, or limb pain, cannot bear weight, or notice a new change in posture. Contact a clinician soon about unexplained persistent back pain or a minor injury followed by intense pain, because these symptoms can need assessment even before a scan is reviewed. A DEXA result itself is not an emergency, but it should not replace evaluation of new symptoms.

Which sites were measured, what do my T-score and Z-score mean for me, and has my bone density changed meaningfully since the previous scan? Do I need an assessment of fracture risk, blood tests, treatment, or a repeat scan?
