Bone Density Scan

Perry County Memorial Hospital (PCMH) offers Missouri residents bone densitometry testing using the established standard for measuring bone mineral density. The test, sometimes called a DEXA scan, is an enhanced form of x-ray technology. It is painless and noninvasive and involves minimal radiation exposure.

The test can be used to:

  • Diagnose osteoporosis.
  • Track the effectiveness of treatment for osteoporosis and other conditions that can cause bone loss.
  • Determine a person's risk for developing a fracture.
After the exam, the images will be interpreted by the radiologist at PCMH. A report will be sent to your physician, who will go over the results with you. Your test results will be in the form of two scores:
  • T score. This number compares the amount of bone you have to a young adult of the same gender with peak bone mass. The T score is used to estimate your risk of developing a fracture.
  • Z score. This number reflects the amount of bone you have compared with other people in your age group and of the same size and gender. If this score is unusually high or low, it may indicate a need for further medical tests.

Preparing for a Bone Density Test

Do not take calcium supplements for at least 24 hours prior to the exam. On the day of the exam, you may eat normally.
