DEXA-Bone Densitometry
Bone Densitometry is a fast, safe, and painless test that uses advanced
technology called DEXA (Dual-Energy X-Ray Absorptiometry)
to measure symptoms of osteoporosis—such as low density and mineral
content of bone—that may have developed unnoticed over many years.
Because osteoporosis can result in bone fractures that can cause chronic
pain, disability, and loss of independence, it is important to begin
treating osteoporosis at an early stage. Bone densitometry can detect
the early signs of osteoporosis so that patients can begin treating it
before a debilitating fracture occurs.
During a comprehensive DEXA bone evaluation, a patient
lies comfortably on a padded table while the DEXA unit scans one or more
areas of his/her body, usually the spine or hip because they are particularly
prone to fracturing. Unlike conventional X-rays, bone densitometry produces
little radiation—less than that produced during a coast-to-coast
airline flight. Bone densitometry is noninvasive, involves no injections,
and, depending upon the number of areas to be scanned, can take just
minutes to complete.
