DEXA Scan
At Health Care Imaging Centre, Meerut, DEXA is usually used to scan the hip, spine, and forearm, where osteoporosis usually starts. The scan uses two low-dose x-rays that move over the areas looked at. The scan will show that some of the x-rays were taken by the bone and some by the tissue. From this, the radiologist can figure out if a patient has osteoporosis by measuring bone mineral density.
Most of the time, DEXA scans are recommended for:
After starting osteoporosis treatment, DEXA scans are often used to check how well the treatment is working. Osteoporosis can't be cured, but treatment should stop the loss of bone density.

DEXA Scan FAQs
We tell people to get a DEXA scan at least once every two years. In some cases, like when someone is taking Fosomax, it may be necessary to do a study every year.
When DEXA scanning was first used, the researchers chose the left hip and lumbar spine. The lumbar spine and left hip were chosen because they have different amounts of cortical bone (bone on the outside) and cancellous bone (bone on the inside). So that all reports are the same, all patients are scanned in these two areas unless a problem prevents this.
If you take calcium supplements close to the time of the DEXA scan, they might not be fully absorbed. The calcium could then go on top of the lower spine and make this area seem denser than it is.
No. You will be lying on your back in comfort. A small sensor will touch your lower back and left hip.
