About the Fellowship


The Thoracic and Cardiac Imaging Fellowship accepts five fellows per year for a one-year fellowship in thoracic imaging, thoracic intervention and cardiac imaging. It consists of nine months of fellowship training in diagnostic thoracic imaging and intervention and three months of dedicated fellowship training in cardiac imaging.

Clinical Experience

The fellowship offers extensive training in digital inpatient chest radiography, digital outpatient chest radiography, thoracic CT, lung cancer screening, dual energy CT of the thorax, 3D imaging, thoracic PET/CT, thoracic MRI, thoracic PET/MRI, thoracic intervention (thoracic biopsy and ablation), cardiac CT, cardiac CTA and cardiac MRI. The Divisions of Thoracic and Cardiac Imaging are supported by a dedicated 3D lab that provides 3D data sets for advanced visualization and diagnosis. The thoracic imaging training occurs in the Division of Thoracic Imaging under the direction of Jo-Anne Shepard, MD, Karen Rodriguez, MD, and the dedicated thoracic imagers of the Division of Thoracic Imaging. The cardiac imaging training occurs under the direction of Nina Meyersohn, MD; Brian Ghoshhajra; MD, and the dedicated cardiac imagers of the Division of Cardiovascular Imaging.

Mass General is a 1,057-bed tertiary care hospital, with multiple intensive care units, including a burn ICU, neuro ICU, medical ICU, surgical ICU, cardiac surgical ICU and cardiac ICU. In addition, Mass General is a Level 1 trauma center, burn center and transplant center, including heart and lung transplantation. Mass General is a major oncology referral center with high volume medical thoracic oncology, pulmonary interventional and general thoracic surgical services. The Division of Thoracic Imaging performs more than 100,000 imaging examinations per year and provides a concentrated experience in both usual and unusual medical and surgical conditions of the thorax. The Divisions of Thoracic and Cardiovascular Imaging work collaboratively with exceptionally strong medical, surgical and subspecialty services.

The fellowship incorporates three months of dedicated cardiac imaging training in cardiac CT, cardiac CTA and cardiac MRI. The Division of Cardiovascular Imaging performs coronary artery calcium scoring, cardiac CTA, cardiac CT for morphology and function and cardiac MRI for a variety of clinical indications. While in the Division of Cardiovascular Imaging, fellows work closely with and receive teaching from experienced and dedicated cardiac imagers.


Imaging Modalities and Clinical Rotations

Training in thoracic and cardiac imaging incorporates all modalities of thoracic and cardiac imaging, including digital inpatient chest radiography, digital outpatient chest radiography, thoracic CT, dual energy CT of the thorax, 3D imaging, thoracic PET/CT, thoracic MRI, thoracic PET/MRI, thoracic intervention (thoracic biopsy and ablation), cardiac CT, cardiac CTA and cardiac MRI.

Fellows rotate through the various clinical assignments of the Divisions of Thoracic and Cardiovascular Imaging, including inpatient chest radiography, outpatient chest radiography, thoracic CT, thoracic MRI, thoracic PET/CT, thoracic intervention, cardiac CT and cardiac MRI.

Interventional Experience

The members of the Division of Thoracic Imaging perform more than 500 percutaneous needle aspiration biopsies per year in a dedicated interventional CT scanner with on-site cyto-pathology support.

Fellows will learn:

  1. The indications for thoracic procedures, procedural risks, benefits and alternatives to the procedure
  2. Patient selection, appropriate use of pertinent pre-procedural tests and the contraindications of the procedure
  3. How to effectively obtain informed consent and adhere to institutional universal “time out” procedural protocols
  4. How to monitor sedation and analgesia, plan an appropriate biopsy approach, recognize pertinent anatomic landmarks, appropriately execute the biopsy, appropriately obtain samples (cytology, core biopsy and microbiology specimens) and recognize intraprocedural complications
  5. The methods of post-procedure patient recovery, recognition and treatment of biopsy complications (including chest tube placement and management of hemoptysis)
  6. The indications and techniques for fiducial marker placement to localize pulmonary lesions for surgical resection and radiotherapy
  7. Thoracic ablative procedures including microwave and cryo-ablation for both primary lung malignancies and metastatic disease to the chest

Consultative Skills

The team teaches fellows to consult with primary care physicians and subspecialists with increasing independence throughout the fellowship year. By the end of the year, fellows learn to be expert consultants in cardiac and thoracic imaging through a variety of conferences and through daily clinical experience.


In addition to the clinical experience and daily teaching, the fellowship also provides didactic teaching.

Thoracic Imaging Clinical Conferences

  • Thoracic Imaging Conference: Weekly conference prepared by the thoracic CT resident of current interesting thoracic CT and thoracic MRI cases. These cases serve as a resource for didactic teaching of residents and fellows.
  • Interstitial Lung Disease Rad-Path Conference: A biweekly conference presented jointly by the Pulmonary Medicine, Thoracic Radiology and Pulmonary Pathology Services. Interesting interstitial lung disease cases are presented with clinical, radiology and pathology correlation.
  • ICU Rounds: Daily ICU rounds with thoracic radiologists and ICU staff in medical, surgical and cardiac intensive care units.
  • PET-CT Conference: A monthly conference presented to discuss chest and abdominal PET-CT cases.
  • Thoracic Surgical Conference: A weekly conference presented by the Thoracic Surgical Service with discussions about radiological correlation and patient management of thoracic surgical conditions.
  • Medical Thoracic Oncology Conference: A weekly conference presented by the Thoracic Oncology Conference with discussions about the diagnosis and management of lung, esophageal and other thoracic tumors.
  • Pulmonary Medicine Conference: A weekly conference in which the pulmonary service reviews radiology studies on its inpatients.
  • Pulmonary Grand Rounds: A weekly conference presented by the Department of Pulmonary and Critical Care Medicine, including case presentations and invited lecturers.
  • Infectious Disease Conference: A conference presented jointly by the Department of Radiology and the Infectious Disease Services. Interesting infectious disease cases are presented with radiology correlation.
  • Cytology Conference: A quarterly conference with interesting biopsy case reviews. The indications, technique and cytology results of thoracic biopsy are reviewed with radiology and pathology in attendance. This conference provides an excellent opportunity to see the yield, usefulness of thoracic fine needle aspiration and core biopsy.
  • Lung Screening Conference: A weekly multidisciplinary conference attended by thoracic radiology, thoracic oncology, thoracic surgery, pulmonary medicine and thoracic radiation oncology. Cases are presented, and multidisciplinary management decisions are made regarding pulmonary lesions found on lung cancer screening or non-screening chest CT exams.

Thoracic Imaging Didactic Conferences

  • Thoracic and Cardiac Mini-Courses: A total of two months of noon lectures focused on thoracic and cardiac imaging. This series of lectures is given to the residents, fellows and staff. Several expert grand rounds speakers are invited as visiting professors.
  • Resident Thoracic Case Conference: A Tuesday morning resident case conference in which the staff present teaching cases to the radiology residents. Fellows may participate in the teaching of residents later in the fellowship year.
  • Thoracic Fellow Conference: A series of didactic fellow-level lectures conducted by thoracic imaging staff in the first six months of the fellowship on advanced thoracic imaging and intervention.
  • Post-Graduate Chest Course: The Departments of Radiology at Mass General and Brigham and Women's Hospital jointly present this post-graduate course. The departments hold this course every other year in November during even years. Internationally renowned speakers traditionally visit as guest lecturers.

Cardiac Imaging Conferences

  • Dedicated cardiac conferences include weekly a Cardiovascular Imaging Seminar, Cardiac Catheterization Conference, Cardiac MR/CT Conference, Congenital Heart Disease Conference and Cardiac ECHO/MRI Conference.
