How much radiation does a DEXA scan use?

Very little: depending on the scanner, a DEXA scan of the hip and lower spine uses about 0.001–0.02 millisieverts (mSv) of X-rays. There is no injection and no contrast agent.

Because the scan uses X-rays, a short pre-consultation before your appointment confirms that it makes sense for you. If you are or might be pregnant, please tell us before booking.
