About This Fellowship


The Division of Nuclear Medicine and Molecular Imaging is proud to offer one of the most comprehensive fellowship programs in the country. Our staff, the wealth of clinical material and interaction with world-class clinicians create an environment to be exposed to all aspects of Nuclear Medicine, Molecular Imaging and Theranostics. Graduates of our program have been successful in both academic and private practice careers.

The program is designed to train the next generation of both academic nuclear radiologists, who will expand the frontiers of medical imaging and private practice radiologists who will bring the most current imaging techniques into community hospitals.

The length of training is 12 months, following completion of Diagnostic Radiology residency. The ACGME approved program leads to eligibility for subspecialty certification in Nuclear Radiology by the American Board of Radiology as well as primary certification by the American Board of Nuclear Medicine.

Departmental and Interdepartmental Conferences

Fellows and residents participate in several didactic conferences which run the gamut from single photon exams to advanced hybrid imaging to theranostic patient selection. Didactic training includes the following topics which meet the hours requirement to serve as an NRC Authorized User: Principles and Clinical Applications of Nuclear Radiology, Medical Nuclear and Diagnostic Radiological Physics, Radiobiology Health Physics and Protection, Nuclear Medicine Instrumentation, Radiopharmaceutical Chemistry and Instrumentation, and Clinical Nuclear Pharmacy.

Division staff and fellows are active in numerous multidisciplinary conferences, which provide extensive exposure to complex oncologic, cardiac, and neurologic pathology.

Theranostic Service

MGH is a SNMMI Therapy Center of Excellence (link) and a major referral center for all cancer types. We have a fully developed Theranostic service line which provides Radium 223, Lu-177 dotatate (Lutathera) and Lu-177 PSMA (Pluvicto) consultations and therapy. Iodine-131 therapy is performed in conjunction with the MGH Thyroid Unit.

Oncologic Imaging

The Department of Radiology at Mass General Brigham has a single enterprise PACS, allowing image review and analysis at multiple different locations, regardless of point of origin across the network. Despite the distributed network across New England, all fellow rotations occur at the MGH main campus. We have state-of-the-art PET and SPECT equipment at the main campus, at our satellite facilities (Chelsea and Danvers), as well as at our affiliates Newton-Wellesley and Salem Hospitals. A Siemens 3T PET/MR is located at the Martinos Research Facility with a clinical scanner breaking ground in 2023-2024. Outside second interpretation consultations obtained at non-Mass General sites provide additional exposure to interesting and complex pathology.

Cardiac Imaging

The MGH Cardiac Perfusion Imaging service based in Yawkey 5 at the MGH main campus has a collaborative relationship with Cardiology. All perfusion SPECT and PET images are interpreted jointly with Cardiology daily. Fellows receive extensive training in Tc-99m SPECT as well as N-13 ammonia and rubidium-82 PET/CT perfusion interpretation.


There is no in-house after-hours call. On-call responsibilities consist of beeper call from home and involve roughly 5 weeknights per month. There is typically no weekend call, which is handled by radiology residents and nuclear radiology staff physicians. When on call, the fellow serves as the first call responder to requests for emergency nuclear medicine procedures. These requests are handled jointly with an on-call nuclear medicine staff physician who provides advice, supervision and review of all aspects of the procedures in real time.

Research Experience

A full range of clinical and research efforts are supported by both single photon and positron nuclear pharmacies. The division’s research operations are focused in the Center for Precision Imaging (link).

Fellows have full use of the educational resources of the hospital’s Treadwell Library and those of Harvard Medical School’s Countway Library.


Applicants to the Nuclear Radiology Fellowship must be enrolled in or have already completed an ACGME-certified Radiology Residency or an equivalent foreign program. By the time of entry into the program, residency must be successfully completed, and the fellow must be eligible for a Massachusetts Limited License. All appointments are contingent upon the fellow obtaining and maintaining this license.

How to Apply

Selection Process
Fellows are selected based on their medical training, general achievements, personal qualities and commitment to furthering the field of nuclear radiology.

Applications for 2026-2027 can be submitted beginning in the fall of 2024.

The selection process involves an initial assessment of your application materials (see below). Selected applicants will be invited for one-day interviews with division staff members and will have the opportunity to get acquainted with our program, working environment and facilities. Interviews for 2026-27 will begin in January of 2025.

International Medical Graduates (IMGs)
Highly qualified international medical graduates who have completed diagnostic radiology training are encouraged to apply for our fellowship, but if they have not completed an ACGME-certified radiology residency, special institutional approval may be required for consideration. Please note: to be considered for a fellowship position, you must have passed the entire USMLE (Steps 1, 2, 3, CSA and TOEFL) and be eligible for a Limited or Full Medical License in the Commonwealth of Massachusetts. Please visit the USMLE and Massachusetts Medical Board for more detailed information.
