Bone Densitometry (DEXA)

Bone Densitometry (DEXA) is currently the most widely used method for measuring the structural integrity of bones. A DEXA scan documents small changes in your bone mass and is most often used to diagnose osteoporosis, a condition that often affects women after menopause but may also be found in men and younger women.

The evaluation of bone health has become an essential component of your personal wellness.

Don’t let osteoporosis sneak into your bones. Let Star MRI of Wayne do your bone density study to stay ahead of this weakening process.

How does DEXA work?

During a DEXA exam the patient lies face up, on a comfortably padded table.

For the test to be accurate, you will need to remain as still as possible during the exam, but will be able to breathe normally. Scanning the spine and femur, sites where fractures occur most often, is considered the standard examination for assessment of osteoporosis. You will not feel anything during the exam as the scanner passes over your lower spine, hip or forearm. The entire test takes only a few minutes to complete. It is a non-invasive procedure that is painless and requires no injections.


Eat normally on the day of the exam, but avoid calcium and vitamin D supplements for at least 48 hours beforehand. If possible, avoid wearing clothing with metal items (buttons, zippers, etc.).

Please inform your physician if you recently had a barium study, a nuclear medicine or oral/intravenous contrast material (such as for an MRI or CT scan). These contrast materials will interfere with the DEXA examination. You may have to wait 10 to 14 days before undergoing your exam. Women should always inform their physician and DEXA Technologist, if there is a possibility they are pregnant.
