Bone Densitometry

What is Bone Densitometry?

Bone densitometry is a medical imaging technique that measures the bone’s density. It involves either X-rays, DEXA (dual-energy X-ray absorptiometry), or an advanced CT scan that can calculate the bone the density of the hip or spine.

It’s used to screen for low bone density, also known as osteoporosis, by measuring how many grams of calcium and other bone minerals are contained in a bone segment. The bones most commonly tested are in the spine, hip, and sometimes the forearm.
