Types of PET Scan
PET scans differ mainly by the tracer used — FDG-PET (using radioactive glucose) is most common for cancer and brain imaging, while specialized tracers like PSMA-PET are used for prostate cancer and amyloid-PET for Alzheimer's evaluation. It is increasingly performed as a combined PET-CT for both metabolic and anatomical detail.
