PET scintillation detector type and photon detection strategy. The ACR claimed the absence of any head-to-head trials displaying just one type of scanning tools top-quality in high quality and value.
The commonest radiotracer is F-eighteen fluorodeoxyglucose (FDG), a molecule comparable to glucose. Cancer cells are more metabolically Energetic and may take in glucose at a greater rate. This better fee could be found on PET scans. This enables your medical professional to detect illness right before it might be found on other imaging exams.
