BMD Patient Information
Your doctor has requested a BMD. Here are some answers to some frequently asked questions.
What is a BMD?
What happens when someone has a BMD?
The machine is often described as looking like a “donut” with a bed sliding through a circular hole.
You will be asked to lie down on a white hard board called a calibration phantom which helps collect the data for the examination. The bed will move during the scan.
The X-rays are emitted from the CT machine and pass through the lumbar spine and hips to create images of this area of anatomy.
Are there any special instructions to be followed before a BMD scan?
How long does a BMD take?
This examination uses X-rays therefore you will need to inform the radiographer before performing the exam if you are pregnant or if there is any possibility you are pregnant.
