Driving directions: By Cars: From I-270 (N or S bound): Take Exit 9A and exit from the FIRST right exit; turn left (east) onto Shady Grove Dr.; turn right (south) onto Rockville Pike (Route 355); turn left (east) onto East Gude Dr.; turn left (north) immediately onto Crabb’s Branch Dr.; turn left (west) immediately onto Standish Place. The first building on your right side is 7519 Standish Place; open parking). The venue is on the first floor of 7529 Building with its external entrance opposite to the left side of 7519 building main entrance. By Metro trains: Off from Red Line Shady Grove Station, and take RideOn Route 59 TOWARD ROCKVILLE and get off from “Calhoun Place” stop. Standish Place is next to the Bus stop. Our venue is within 2 min of walking distance from the stop.
Positron emission tomography (PET) is a nuclear medicine image technique.  Molecules (e.g., drugs) labelled with positron-emitting radioisotopes, called radioligand, are injected into human body, following regular pathway of the drug.  During the time course, annihilation continues to occur when the positron captures an electron, generating two opposite flying photons.  The “paired” photons are detected by the scanner.  Reconstruction of these “coincidence events” yields a “functional” image which allows us to study the pharmacokinetics of the drugs and/or the pathophysiology of the organs.
The most common “radio-labelled drug” for PET is fluorine-18 labelled flurodeoxy glucose ([18F]FDG).  After injection, this radioactive glucose is taken up by cells similar to regular glucose.  However, after metabolism, it gets trapped, accumulating in the cells.  PET image of [18F]FDG is basically a consumption map of glucose which can reveal abnormal glucose metabolism (in dying neurons – hypometabolism or in cancer cells – hypermetabolism) .  Other molecules that can be used as a candidate probe for radiolabeling include antibodies, enzymes, or any drugs that interact with the biological system.  Mission of the Molecular Imaging Branch at National Institute of Mental Health (NIMH) is to develop novel radioligands for studying various psychiatric and neurological disorders.
