DEXA Scanning (Bone Density Scan)
A complete DEXA service for bone density assessment is available. Scanning is available 5 days a week with virtually no waiting lists and same day reporting. We report scans with a Bone Mineral Density (BMD), BMD of healthy young adults (T score) and with that expected of a healthy patient of the same age (Z-score) and compare all data to any prior imaging. (BMD g/cc).
DEXA stands for Dual Energy X-Ray Absorptiometry. The test measures the density of bones to show how strong they are, helping to diagnose osteoporosis and establish an individual patient’s risk of a fracture. DEXA sends low energy X-Rays from two different sources through the bone being tested, usually the lumbar spine and the hips. The denser the bones, the less X-rays get through.
There is no special preparation for the scan. The radiographer will ask you to fill out a questionnaire giving some relevant details about yourself. You lie on your back on a firm couch and are asked to keep still. A detector bar moves over the areas to be tested. The test takes about 15 minutes to complete.
Your doctor may request a DEXA scan if you are at increased risk of osteoporosis. If diagnosed, treatment can be commenced to strengthen the bones and lower the fracture risk.
People at risk include those who have:
Most DEXA appointments can be facilitated on the same or next day of the referral. A referral letter from your doctor is required at the time of the scan unless otherwise instructed. To make an appointment please see our contact section.
