DEXA Scanning for Osteoporosis |
 What is a DEXA scan? Dual Energy X-ray Absortiometry (DEXA scanning) is the most widely used method to measure how many grams of calcium and other bone minerals are packed into a segment of bone. The higher the mineral content, the denser and stronger the bone is and less likely to break. A bone density test is used to determine if you have, or are at risk for osteoporosis. A DEXA scan is currently the most accurate test available.
Osteoporosis can pose a special threat to women because as we approach menopause our body produces less Estrogen, the hormone that protects against bone loss. "Shrinking" in height, slight curving of the back, back pain or tenderness are symptoms of osteoporosis. And, as the spinal bones weaken, they slowly collapse under the weight of the upper body, causing the spine to curve - often referred to as "dowager's hump."
Before the test, you will be asked to fill out a questionnaire that will provide helpful information in the analysis of your scan. You'll need to remove metal objects (jewelry, hair clips, etc.). You can keep your clothing on during the scan.
During the test, you will lie on the table for 3-15 minutes while an arm-like device called an imager, scans your body.
Radiation exposure is less than one tenth the amount in a normal chest x-ray. No recovery is needed after the test.
The results of your scan will be sent to your provider. If your scan indicates low bone mass, he/she will discuss the treatment options available. |
