|Bone Density (DEXA)|
DEXA stands for Dual Energy X-ray Absorptiometry. A DEXA scan produces an intense narrow beam of radiation that quickly and precisely measures bone density. This test is the best technique available to diagnose osteoporosis. Osteoporosis is a disorder of the bones characterized by a progressive loss of bone tissue, which can result in an increase in the risk of fractures. Though a routine x-ray examination can reveal osteoporosis, by the time this is detected on a conventional x-ray the disease may have progressed significantly.
A DEXA scan is a safe, painless, and non invasive exam. It is a very simple test. The technologist will position you on the exam table to measure the bone density of the hip, spine, or forearm. The computer will calculate your score and from this information the radiologist can diagnose whether your bones are showing signs of osteoporosis.
It is recommended that patients have a base line scan at 45-50 years of age. All follow up scans can be compared to the first scan to monitor the changes of the bone density.
