What is Bone Densitometry (DEXA)?
Bone Densitometry (DEXA) evaluates the density of bone — meaning the bone mineral density in a given unit of bone (grams per centimeter, for example). Below-normal bone density can indicate problems such as calcium loss from osteoporosis, a condition most common in women after menopause, but one that sometimes affects men or younger women.
RMI offers a state-of-the-art method of bone densitometry called DEXA, which uses an advanced form of x-ray technology to provide information about the thickness of bones by measuring their absorption of the x-rays. DEXA stands for Dual-Energy X-Ray Absorptiometry.
In addition to scanning bone density, RMI’s radiologists have the ability to treat patients suffering from back pain caused by an osteoporotic fracture. It is available via fairly quick outpatient procedures known as kyphoplasty and vertebroplasty.
Preparing for Bone Densitometry (DEXA)
Unlike other medical examinations, no special preparation is required. There are no needles, dietary restrictions, or other preparation. Patients will need to bring their referring doctor’s order form, ID and insurance information, and dress in comfortable loose clothing that does not have metal.
The exam usually takes 20-30 minutes.
