Appointments are required for all exams except X-ray, which is offered on a walk-in basis. Requisitions are required for every appointment.

Bone Mineral Densitometry

Bone mineral densitometry (BMD) is a low-dose X-ray exam that measures bone density to determine if you are at risk of fractures or have osteoporosis. This exam is also known as dual-energy absorptiometry or DEXA scan.

A BMD exam involves a thin, low-dose X-ray beam with two distinct energy peaks being passed through the spine, hip, or forearm. One peak is absorbed mainly by soft tissue and the other by bone. Special computer software can subtract the soft tissue information and display bone density measurements, such as how many grams of calcium and other bone minerals are in a square centimeter of bone. Generally, the higher the mineral content, the denser the bone is, and the denser the bones are, the less likely they are to fracture.

Low bone density may be a risk factor for osteoporosis - a disease where bones lose density which can lead to fractures, pain, and deformities. Early detection is important because you may not even notice you have it until you sustain a painful fracture.


    • In addition to adults, children ages 5-19 can be scanned at all clinics.
    • Please make sure to tell your technologist and doctor if you’re pregnant.
    • The bed we use has a maximum weight capacity of 147 kilograms (325 pounds). If weight restrictions prevent you from using the scan table, a wrist exam will be performed.
