Overall Projects and Goals

Pancreatic Cancer Prostate Cancer 5-year survival rate: 6% 4 th leading cause for cancer-related death in Western countries No reliable method for early detection (yet) Standard procedures: Ultrasound and CT scans  Lack metabolic information 6 th leading cause for cancer-related death amongst male population worldwide Good prognosis if cancer confined to prostate and treated aggressively Standard procedures: Ultrasound and MRI  Lack metabolic information Focus

Ultrasound

Typical Full-Body PET Scan Fluorodeoxyglucose (FDG) injected into body FDG is basically radioactive glucose Cancerous cells process glucose differently to normal cells FDG releases positrons, which break down and release gamma waves PET scanner detects gammas Images from scan highlight how FDG is broken down in body, giving insight into tumors’ metabolism TOF = Time of Flight LOR = Line of Response
