What is a DEXA scan?

A DEXA scan provides highly accurate measurements that can help identify osteoporosis, assess fracture risk, monitor bone health, and provide detailed insights into body fat, muscle mass, and overall body composition.

At Canopy Imaging, we offer two types of DEXA scans: Bone density scans and Body composition scans.

Bone Density Scan

A bone density scan measures bone mineral density using low-energy X-rays, helping to diagnose osteoporosis and assess fracture risk.

Pre Examination

Before your examination

  • Please call us to make an appointment for your scan
  • Please wear clothing without buckles, buttons or zips
  • If you have a referral from your doctor please bring this with you

Your Examination

When you have your scan a skilled, qualified technician will ask you to lie on a special bed. You will hear a quiet machine noise and a scanning arm will move above you, but will not touch you. The technician will tell you when the scan is finished. The scan takes about 20 - 40 minutes.

Post Examination

Your scan results will be interpreted by the Radiologist and a report will be sent directly to your doctor who will discuss the results with you.
