Benefits and Risks – Dual-energy X-ray Absorptiometry (DXA, previously DEXA)

Benefits

Dual-energy X-ray absorptiometry (DXA, previously DEXA) is a simple, quick and noninvasive procedure.
No anesthesia is required.
The amount of radiation used is extremely small—less than one-tenth the dose of a standard chest x-ray, and less than a day's exposure to natural radiation.
DXA testing is the most accurate method available for the diagnosis of osteoporosis and is also considered an accurate estimator of fracture risk.
DXA equipment is widely available making bone densitometry testing convenient.
No radiation remains in a patient's body after an x-ray examination.
X-rays usually have no side effects in the typical diagnostic range for this exam.

There is always a slight chance of cancer from excessive exposure to radiation. However, the benefit of an accurate diagnosis far outweighs the risk.
Women should always inform their Radiologist if there is any possibility that they could be pregnant.
The effective radiation dose for this procedure varies.
No complications are expected with DXA.
