Bone mineral densitometry
A bone mineral densitometry (BMD) scan is used to check the level of calcium in the bones. BMD scans are useful in diagnosing osteoporosis, predicting the risk of fracture and assessing the response to osteoporosis treatment.
The measurements are commonly made over the lumbar spine, upper femur and sometimes the forearm and even the whole body if required.
Measurements are compared against a population of people of the same size, sex and ethnic background.
The scan is painless and non-invasive, and takes place on an examination table.
