Understanding DEXA Scans
A DEXA (Dual-Energy X-ray Absorptiometry) Scan is a type of imaging test that measures bone density. It uses low-dose X-rays to differentiate between bone and soft tissue, allowing it to accurately calculate bone density.
Purpose and Benefits of a DEXA Scan
The primary purpose of a DEXA Scan is to diagnose or assess the risk of osteoporosis, a condition that weakens bones and makes them more likely to break. By detecting low bone density early, appropriate treatment can be initiated to strengthen the bones and reduce the risk of fractures.
Conditions Detected by a DEXA Scan
In addition to osteoporosis, a DEXA Scan can also detect other conditions related to bone density, such as osteopenia. It can also be used to monitor the effectiveness of treatment for these conditions.
