PET / CT with Ga-68-PSMA for prostate cancer

Diagnostic procedure

In a detailed interview, you will discuss with one of our doctors your symptoms, examinations conducted so far along with treatments, as well as the procedures that will be used in the scheduled examination.

Following this, an intravenous injection will be made into a vein in your arm containing a trace of a radioactively labelled substance that accumulates in metabolically active prostate tissue/metastases. The substance used is very well tolerated. Allergic reactions are not documented. The radiation exposure is comparable to a diagnostic CT of the spine. 

Then you can relax in our waiting room and should drink at least 1 litre of mineral water. This is readily available at our office.

About 60 minutes later, whole-body imaging, including CT, will be performed. The imaging is performed while lying down and will take about 45 min. It is done with a so-called PET scanner. This device has no closed tube, but two separate ring systems which are arranged one behind the other with some spacing. In between these the unit is open. Therefore, the imaging is usually well tolerated even for people who are claustrophobic. Throughout the investigation you will be looked after by one of our medical technologists, who will be in permanent earshot.

The results of the examination are evaluated by the attending physician on a monitor, individual images are printed out on paper and  the entire record of the investigation is archived onto a CD-ROM.

In a conversation afterwards, the attending physician will discuss with you the findings. As a rule, you will receive the doctor's report, the images taken, and the CD-ROM.


On the day of the examination it is not necessary to abstain from food and drinks. For the examination, you make take medications as directed by your treating physician.

The radiopharmaceutical is prepared individually for patients and can not be stored. Therefore, punctuality is absolutely essential.
