Risks and Contraindications
- By and large, a DEXA scan is a very safe test. Although it does involve exposure to radiation, which always carries a slight risk of cancer, the levels of radiation you are exposed to during a DEXA scan are about the same amount as you would encounter while on a transcontinental airline flight, or a tenth of the amount of radiation emitted during a chest X-ray.7 What's more, according to th…

- The better prepared you are before you have a DEXA scan, the smoother and easier the procedure will go. Timing: The DEXA scan itself takes only 10 to 30 minutes, depending on the part of the body being examined. However, you will want to allow more time than that, as you will probably need to fill out a few forms when you arrive for your appointment. You'll also need a bit of time t…
