A PSMA PET/CT scan is a highly sensitive scan used to detect prostate cancer that has spread to other parts of the body. It combines results of two scans – CT scan and a PSMA PET scan – into one image.
PSMA PET/CT scans can pick up very small cancers that other types of scans may miss.
PSMA PET/CT scans are most useful when:
PSMA PET/CT scans are also currently used in trial settings to diagnose prostate cancer and during active monitoring of low-risk prostate cancer. They are not yet generally used as a diagnostic tool.
There are no significant risks of a PET CT. Some patient may experience headache, taste changes or fatigue but they are generally short lived.
Before your scan, make sure you drink at no more than one litre of water and have consumed just a light meal. Wear loose, comfortable clothing, as you will need to change into a gown.
Your specialist will give you more specific instructions about how to prepare.
Here’s what to expect on the day of your scan:
You can resume your normal activities after your PSMA PET/CT scan, and you can drive home, unless you had medication that put you to sleep (sedation). Aim to avoid pregnant women and children for 2 hours.
A report and a disc of images will be forwarded to your specialist. They will review your results and make a follow-up appointment with you as soon as possible.
