Bone density scan (DEXA, DXA)
DEXA scan stands for dual energy x-ray absorptiometry. It’s also called a bone densitometry scan. It uses low dose x-rays to take measurements to work out the strength (density) of your bones. You have a DEXA scan in the x-ray (radiology) or nuclear medicine department of the hospital. A radiographer does the scan. It takes about 10 – 20 minutes. You’re not enclosed in a small place as the machine has an arm that hangs over the scanning couch. Why might you have a DEXA scan? You might have this scan if you’re having or have had cancer treatment that
