Ga-68 PSMA PET/CT
PET/CT is a hybrid imaging procedure combining positron emission tomography (PET) and computer tomography (CT). In Ga-68 PSMA PET/CT examination, a radioactive compound, consisting of the diagnostic positron emitter Gallium-68, and a ligand targeting the prostate specific membrane antigen (PSMA), is used to detect prostate cancer and its metastases. It is an obligatory procedure to assess whether a patient is suitable for PRLT. Furthermore, it also plays an important role in the follow-up after PRLT.
What should be considered before a PET/CT examination is performed?
First of all, it is important that your attending physician completes the registration form for PET/CT examinations (Download form) and returns it to us.
How is a PET/CT examination performed?
The radiopharmaceutical (Ga-68 PSMA) is injected via an intravenous access.
After the injection, there is an approx. 60-minute waiting period. During this time, you will be given an oral contrast medium to drink so that the bowel can be demarcated. The actual PET/CT examination lasts about 20 minutes in total, whereby first, the radioactivity is measured using PET, followed by the CT examination with possible administration of contrast medium via the vein.
What do I have to consider as a patient?
For the Ga-68 PSMA PET/CT examination, you must be fasting for about four hours due to the possible administration of a CT contrast medium during the study.
Please bring along (if not submitted in advance) all reports (histology, surgery report, doctor's letters, tumor markers, etc.) and, if applicable, the CT/MRI images (on a CD) with you.
Please also let us know if you have a thyroid disease, kidney disease or an allergy to contrast media.
