Nuclear Medicine - Prostascint Scan

What is a Prostascint Scan?

A Prostascint scan is a specialized Nuclear Medicine exam used to diagnose prostate cancer, reoccurrence of prostate cancer, or metastatic prostate disease after the IV injection of a radioisotope.

What are some common uses of the procedure?

A Prostascint scan is used to evaluate an enlarged prostate detected by an abnormal CT or Ultrasound, or after there has been an increase in prostate cancer markers or a raising PSA level after a previous surgery or therapy.

How should I prepare for the procedure?

No special preparation is required the day of the injection.  A low fiber diet will be followed for 96 hours (4 days) after the injection.  You will have only a clear liquid diet on the 3rd day after 7:00 pm.  One of three laxatives will be taken the night before the scan at 9:00 pm.  A Fleets enema will be completed at 5:00 am the day of the scan.

How is the procedure performed?

A low dose isotope of In-111-Prostascan will be injected over 5 minutes, and normal saline will be infused over 20-30 minutes through an IV.  You will return 96 hours (4 days) later for images to be obtained.  Blood will be drawn and tagged with 99mTc and re-injected.

How long will the procedure take?

You should expect to be in the department for about 3 to 4 hours on the day of your scan.  Whole body imaging will be completed for 20-30 minutes.  Two 1 hours SPECT scans will be done, as well as a 30-40 second non-diagnostic CT scan.

Who interprets the results and how do I get them?

A radiologist will interpret the results from your exam, and a signed report will be sent to your physician who will discuss the results with you.
