Imaging Services - Bone Densitometry

Bone density scanning, also called dual-energy x-ray absorptiometry (DXA) or bone densitometry, is an enhanced form of x-ray technology that is used to measure bone loss. DXA is today's established standard for measuring bone mineral density (BMD).

DXA is used to determine the density of your bones. DXA is most often performed on the lower spine and hips. Peripheral devices that use x-ray or ultrasound are sometimes used to screen for low bone mass. In some communities, a CT scan with special software can also be used to diagnose or monitor low bone mass (QCT). This is accurate but less commonly used than DXA scanning.

As we age our bones can become brittle and porous. Osteoporosis is a disease in which the body’s bones become extremely porous and brittle.  Osteoporosis is a leading cause of disability among older people, particularly elderly women. Bones weakened by mineral loss are prone to fractures, especially in the spine and hip. This is especially common in women following menopause. Even though Osteoporosis is typically believed to be an issue only for women, men are  prone to developing the disease as well. It is important for patients to understand this disease in order to help prevent bone loss.
