Pancreatic cancer is a very aggressive cancer, often associated with poor prognosis usually due to patients being diagnosed when the disease is advanced. Cancer staging / re-staging is the process of determining how much cancer is in the body and where it’s located. This process is critical in ensuring patients receive the most appropriate treatment for their cancer. This is done by a variety of methods including using a tracer in PET / CT imaging. However pancreatic cancer is notoriously difficult to image using this method. At this time there is no alternative tracer for sensitive and specific imaging of pancreatic cancer. This study aims to establish a useful imaging tracer for pancreatic cancer patients. This will mean these patients will have an effective imaging option which will better inform their treatment planning, compared to current standard care.
