What is Bone Density?
Bone densitometry is a fast, painless exam that measures the bone mineral density (BMD) of your bones.  You simply lie on your back and the machine takes the measurements in a couple of minutes.

      Is the exam safe?
The exam involves subjecting the body to a very small dose of radiation-- much less than the body is exposed to in the environment over the course of the year.  As with any radiology procedure though, if you are pregnant you must inform the Technologist or Radiologist prior to the procedure.

      Are there different types of Bone Density tests?
There are different types.  Some use a machine called a DEXA machine and others like ours uses CT technology called QCT-3000.  The QCT method has been shown to be more accurate because it specifically targets the part of the bone that first undergoes changes of osteoporosis.

      Are there any preparations?
No.  You do not have to fast.  You should wear clothing free of metal (zippers, snaps) which will interfere with the exam.  In such cases, you would have to change into a gown.

      What happens after the exam?
Your doctor will receive a graph and report within 24 hours indicating your BMD and your risks of developing osteoporotic related bone fractures.  You may resume normal activity.
