Bennett S. (Ben) Greenspan, M.D., M.S. received his M.D. degree from the University of Illinois in Chicago. He was a resident in Diagnostic Radiology at the West Los Angeles V.A. Medical Center, and a resident in Nuclear Medicine at the Sepulveda V.A. Medical Center, both UCLA affiliates. He received his M.S. degree at UCLA in Medical Physics. He is certified in Diagnostic Radiology and Nuclear Radiology by the American Board of Radiology and in Nuclear Medicine by the American Board of Nuclear Medicine. Dr. Greenspan is a Fellow of the American College of Nuclear Physicians (ACNP), American College of Radiology (ACR), and the American College of Nuclear Medicine (ACNM). He has served as President of ACNP, MVCSNM, the Missouri Radiological Society (M.R.S.), and the SNM Academic Council.
In addition to the SNM Board of Directors, he currently serves on the Boards of the SNM Physics and Instrumentation Council, ABSNM, ICACTL, ACNM, Academy of Radiology Research, and the Executive Councils of MVCSNM and M.R.S. and has previously served on the Executive Councils of the ACNP and the ACR InterSociety Summer Conference. He serves as an oral board examiner for the ABR and an item writer for the ABR and ACR. He serves on the Accreditation Committee for Medical Physics graduate programs and is a member of two committees of the AAPM on teaching medical physics to radiology residents and development of the medical physics curriculum for radiology residents. He also is a member of the AAPM Nuclear Medicine Subcommittee. He is a member of the Molecular Imaging Education Task Force of SNM, which is working to shape the future curriculum for Nuclear Medicine residency. He is a reviewer for quality assurance in Nuclear Medicine for the ACR. He has been an active member of SNM, ACNP (now ACNM), ACR and RSNA for over 20 years, and serves on numerous committees and task forces - for SNM and ACNP: Continuing Education, Procedure Guidelines, and Government Affairs committees, and the CT Task Force. For ACR, he is a member of the Nuclear Medicine Commission and the Guidelines and Standards Committee for Nuclear Medicine. He is a member of the Scientific Program Committee for RSNA and AUR.
Dr. Greenspan is devoted to teaching of clinical nuclear medicine and also physics of nuclear medicine to nuclear medicine and radiology residents. He was the Radiology Residency Program Director for four years at the U. of Missouri, Columbia, and served as Associate Program Director of Nuclear Medicine at the Mallinckrodt Institute of Radiology of Washington University in St. Louis. Dr. Greenspan's research interests include PET imaging in oncology, osteoporosis, and the effects of low level radiation. He has been a co-investigator on 11 grants.
