A bone density scan—also called a DEXA scan —is used to determine if you have or are at risk for osteoporosis. If you have already been diagnosed with osteoporosis, your doctor may refer you for a bone density scan to determine if your treatment is working or if your condition is getting worse. This test can performed quickly at an imaging center in San Antonio and is completely painless.
Your bone density results are expressed as T-scores. If your T-score is -1.0 or greater, then your bone density is normal. T-scores between -1.0 and -2.5 suggest that you have low bone density. If your T-score is -2.5 or less, then your doctor may diagnose you with osteoporosis. If you are sent for a DEXA scan after you have already been diagnosed with osteoporosis, your doctor will check to see if your T-score has improved, which suggests that your treatment is working. If your T-score has gotten worse, it means you have suffered further bone loss and may need another kind of treatment.
