All PET imaging and PET studies at the Center for Neurosciences, including the PET Imaging Core conducted for projects done by the National Institutes of Health Morris K. Udall Center of Excellence for Parkinson’s Disease Research at The Feinstein, is directed by Dr. Vijay Dhawan; the radioactive material license for operating the facility is issued to Dr. David Eidelberg, the Program/Laboratory Director. Drs. Eidelberg and Dhawan have worked together for many years, and have extensive experience running NIH-sponsored human studies involving quantitative PET imaging. The PET facility also employs three nuclear-medicine technologists.Studies are conducted on a GE Advance PET camera, which scans and records the concentration of radioactive trace isotopes with a total of 12,096 bismuth germanate crystal detectors mounted on 18 detector rings. The camera generates 35 simultaneous slices 4.25 mm apart.
