Before the test begins, your head may be taped to the table to prevent any movement. Even slight movement can change the picture. The table then slides into the MRI machine for the test to be done. If you have any concerns about claustrophobia, speak with your doctor before the test. The technician, who is watching you from the control room, will also help you by talking to you during the test.
Ear plugs are available.
The test should take approximately one hour. Your attending physician will discuss the results with you. A dexa scan is an examination that measures bone mineral density. The scan is performed on a machine designed exclusively for bone density measurement. Dexa scanning requires only a small amount of radiation.
