What you should know
Bone density scanning, also called dual-energy x-ray absorptiometry (DEXA) or bone densitometry, is an enhanced form of x-ray technology that is used to measure bone loss. DEXA is an established standard for measuring bone mineral density (BMD).
DEXA is most often performed on the lower spine and hips. In children and some adults, the whole body is sometimes scanned. Peripheral devices that use x-ray or ultrasound are sometimes used to screen for low bone mass. A CT scan with special software can also be used to diagnose or monitor low bone mass (QCT). See CT Bone Density, which is an accurate but less commonly used method of determining bone mineral density.
What is a CT bone density scan?
A CT Bone Density scan (QCT) is an extremely accurate way to diagnose osteoporosis and determine your risk for a future fracture. Learn More
