Densitometry

An imaging technique that uses low-dose X-rays to measure bone density, as determined by the concentration of calcified material. It is used to diagnose and assess the severity of osteoporosis, especially in the spine and femur, and to assess its response to treatment. During the procedure, X-rays are passed through the body. A computer assesses the amount of X-rays absorbed by the body and uses this information to calculate the bone density.
