The Nuclear Medicine Division in the Department of Radiology at University Hospitals/Case Western Reserve University offers two nuclear radiology ACGME (Accreditation Council for Graduate Medical Education) approved fellowship positions per year. The fellowship program meets all training requirements recommended by the American Board of Nuclear Medicine. Our division consists of four full-time nuclear medicine subspecialty trained academic faculty and over 20 specialized nuclear medicine technologists. We share a strong commitment to education, expressed through training of radiology fellows, residents, and medical students.

Education and Technology

The Nuclear Medicine Division is committed to excellence in imaged-based clinical care. Our health system is comprised of over 15 hospitals and the majority of all nuclear medicine studies are interpreted at University Hospitals Cleveland Medical Center. We provide a full spectrum of diagnostic imaging with state-of-the-art equipment, including 5 PET/CT scanners, digital PET/CT, and PET/MR. Additionally, we are equipped with the latest Discovery NM/CT 870 DR and the 670 CZT digital SPECT/CT system. We offer comprehensive radionuclide diagnostic procedures and therapies including I-131, Ra-223 Xofigo, Y-90 Zevalin, Y-90 microspheres and Lu-177 Dotatate. We utilize a variety of advanced software tools for diagnostic work including MIM Radiology & Nuclear Medicine, GE Xeleris, Philips Intellispace, and Sectra PACS.


The fellowship program includes training in general nuclear medicine, pediatric nuclear medicine with UH Rainbow Babies & Children's, nuclear cardiology with UH Harrington Heart & Vascular and positron emission tomography (PET) with UH Seidman Cancer Center. It also teaches the safe handling and use of unsealed radioactive drugs for medical purposes which involves quality control and quality assurance training. There are weekly conferences covering all aspects of nuclear medicine as well as weekly journal clubs and seminars. Trainee responsibilities increase progressively throughout the year, from close supervision during the first six months of training to greater independent responsibility later on.

Research Opportunities

Our staff are all active in research and clinical innovation in the Society of Nuclear MedicineRadiological Society of North AmericaThe American Society of Nuclear Cardiology, and the American College of Radiology. Our division has access to a cyclotron and is operating a new human use PET radiopharmacy for the development of new molecular imaging agents. There are plenty of research opportunities in the use of experimental PET radiopharmaceuticals together with either PET/CT or PET/MR. We currently have an Investigational New Drug (IND) clearance from the FDA for F-18 fluorothymidine (FLT) and Ga-68 PSMA to explore early cancer therapy response assessment.


Fellowship specific benefits include salary at a PGY-6 level, 4 weeks of paid vacation, and funding to attend one conference per year. Additional employee benefits are detailed under the Graduate Medical Education section.


We aim to train highly motivated and dedicated applicants from throughout the country. The ideal candidate has a strong work ethic, is internally driven and is a team player.
