Bone Density Screening

What types of bone density screening does Valley Radiology offer?
Valley Radiology Consultants offers DEXA and QCT.

What is DEXA?
DEXA, performed using x-ray, is an exam used to measure bone loss. It is the established standard for measuring bone mineral density (BMD).

What is QCT?
QCT, or Quantitative Computed Tomography, is an exam used to measure bone mass using a CT machine. Unlike other forms of bone density testing, QCT measures the metabolically active trabecular bone for analysis.

How should I prepare for a DEXA or QCT?
You can eat normally on the day of your exam. Please wear loose, comfortable clothing and avoid anything that has zippers, belts, buttons, or anything made of metal. You may be asked to remove your jewelry, eye glasses and any other metal objects before the exam. You may also be asked to remove your clothing and put on a gown.

Should I get a bone density screening exam?
Your physician should determine whether a DEXA or QCT is appropriate for you. If you have concerns about your bone density, please talk to your primary care physician about which test is best for you.

Who interprets the results?
A board certified radiologist will analyze the images and send a signed report to your primary care or referring physician, who will share the results with you.
