Often called the silent disease, osteoporosis robs the body of bone strength, leaving many at risk for broken bones with even a simple fall or bump. Post menopausal women are at highest risk but both men and women lose bone strength as they age. In recent years, the emergence of many new pharmaceutical options has greatly enhanced the treatment of osteoporosis. With these new treatment options available, diagnosing bone loss early can have a significant impact on quality of life for osteoporosis patients.
DEXA bone density scans make use of a specialized x-ray technology to obtain focused images of the hip and lower spine. This is the area where osteoporotic fractures occur most often. The x-ray beam itself is made up of two distinct energy levels that are absorbed differently by the bones. These images are sent directly to a computer that analyzes the differences and calculates the amount of bone mineral present. Using sophisticated computer software, this information is then compared to national measurement standards and a profile is generated detailing the level of bone loss and the potential risk for bone fractures.
Your potential risk is expressed in two measurements or scores. The first is a T score that compares your bone mass with that of a healthy young adult. Any score above -1 is considered normal. A score between -1 and -2.5 indicates low bone mass or osteopenia, the precursor to osteoporosis. A score below -2.5 is defined as osteoporosis.
The second measurement is a Z score. This number compares your bone mass with other people in your age group. If this score is unusually high or low, your physician may recommend additional medical tests.
