Is bone density scanning safe?
Norwalk Radiology utilizes Dual Energy X-ray Absorptiometry (DEXA) technology, which offers an extremely low x-ray dose. The amount of radiation for a bone density scan is only a fraction of that received from a standard chest x-ray. It is comparable with the amount received on a transcontinental flight. The DEXA method produces less radiation than other methods such as QCT. Although DEXA emits a very low amount of radiation, always inform the technologist if there is a chance of pregnancy.
