The T-score results from a special type of X-ray called a Dual Energy X-ray Absorptiometry (DEXA for short) which examines a person’s bone density to discover how much has been lost. This is a non-invasive procedure which sees you lying on a firm hospital couch and having x-rays passed over the relevant parts of your body. The machine will measure the X-rays that your bones absorb, and the result is your T-score.
