PET-CT (Positron Emission Tomography with Computerised Tomography) is a scanning method that allows us to detect abnormalities in the body. For this scan an injection containing a small amount of radioactivity called Ga68 (Gallium-68) which helps us to identify certain types of tumours is administered to the patient.
There are 2 types of Ga-68 scans:
- Ga-68 DOTATATE scan – for neuro endocrine tumors
- Ga-68 PSMA scan – for prostate tumors
Ga-68 will be tagged with either the DOTATATE peptide or the PSMA before being injected to patients.
