Reasons for Test    TOP

This test is given to men who have prostate cancer to see if it has spread to the lymph nodes or other areas.

Possible Complications    TOP

Problems from the procedure are rare, but all procedures have some risk. Your doctor will review potential problems, like:

  • Changes in the levels of bilirubin (a waste product) in the blood
  • Changes in blood pressure
  • Allergic reaction

What to Expect    TOP

Prior to test

Your doctor may do a bone scan. This is a test that detects areas of increased or decreased bone turnover. It can reveal bone injury, bone disease, or cancer spread to the bones.

Before your test:

  • You will come in 4-5 days before the scan for an injection of radioactive isotope into your vein.
  • Follow your doctor’s advice for cleaning out your bowel. You may need to take a laxative or enema the night before.
  • You may need to have your bladder emptied of urine by a urine catheter.

Description of the Test

For the scan, you will be positioned next to a device that takes images.

The radioactive material that was injected into your vein is attracted to prostate cancer cells in the body. Whole body images will be taken to detect areas where the material collects. This is done to find out if the cancer has spread to lymph nodes or other organs away from your prostate.

After Test    TOP

You will be able to leave after the test is done. You can resume normal activities. You may need to return the next day for more images.
