Prostascint Scan

What is a Prostascint scan?

A Prostascint scan is use to evaluate patients with biopsy-proven prostate cancer to determine the extent of disease.

How should I prepare for a Prostascint scan?

The day prior to imaging you will be asked to remain on a clear liquid diet. You will also have to drink a 10oz bottle of Magnesium Citrate between 4:00-6:00 pm the evening before your day of imaging. These instructions will be given to you the first day you arrive to the Department of Nuclear Medicine for your injection. There is no prep prior to injection.

How long does the test take?

You will need to make two visits to the Nuclear Medicine department in order to complete this test. The first visit you will be given a small injection of a radioactive isotope in a vein followed by a short imaging scan. You will then leave the department and be asked to return four days later for your scan. You will be given some instructions to follow during those four days which are outlined above. When your return to the department you will be asked to remove all external metal and scanned from your head to mid-thigh. This scan takes about 20 minutes. Then the technologist will take a series of images called a SPECT/CT. This is a tomographic scan combines with a nondiagnostic CT used for attenuation correction and takes approximately 60 minutes.

How soon will the results be available?

A radiologist will interpret the images, write a report, and deliver the results to your doctor via the internal computer system. This process usually takes less than 24 hours.

It is essential to tell your doctor if you are pregnant or think you might be pregnant before undergoing this scan because of radiation exposure.
