Understanding Dexa Scan Results
Considerations
Since you can have osteoporosis and not have any symptoms, it is important to get tested on a regular basis to make sure you are not losing bone density. A Dexa scan measures the bone mineral density in your hips, spine, wrists and heels. The results of this test predict your likelihood of suffering from a fracture. Those with moderate to severe osteoporosis can get a fracture from simply sneezing, bending forward or twisting movements.
T-Score Numbers
Your Dexa report will have a series of numbers. The most important is the T-score. A T-score between +1 and -1 is considered normal. A T-score between -1 and -2.5 indicates that you are beginning to lose bone density. This is the beginning stage of osteoporosis, called osteopenia. A T-score of -2.5 or lower confirms that you have osteoporosis. Scores of -3.8 or more is considered severe osteoporosis.
Z-Score Numbers
Your Z-score is a comparison of your bone density to what is normal for someone your same age and body size. The Z-scores is not used to diagnose osteoporosis in those over age 50. Among older adults, low bone mineral density is common, so Z-scores can be misleading. An older person might have a "normal" Z-score but still be at high risk for breaking a bone. Z-scores are be more helpful in younger men, premenopausal women and children. A Z-score above -2.0 is normal
