Radiopharmaceutical Chemistry: From the Bench to the Bedside Neil Vasdev, Ph.D., Assistant Professor of Psychiatry, University of Toronto & Senior Scientist (Radiochemist), PET Centre,Centre for Addiction and Mental Health The Centre for Addiction and Mental Health and University of Toronto have an established history in the synthesis of radiopharmaceuticals from "bench to bedside" for clinical Nuclear Medicine. Positron Emission Tomography (PET) is a medical imaging technique that uses "drugs" labelled with short-lived radioisotopes such as fluorine-18 (half-life of 2 hours) and carbon-11 (half-life of 20 min). Basic chemistry research is critical to advance the development of new radiopharmaceuticals. This presentation will focus on rapid, multi-step synthetic chemistry that our laboratory develops to prepare radiopharmaceuticals for imaging patients suffering from psychiatric disorders and cancers.
