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.
