Pediatric Cardiovascular Imaging Fellowship

Pediatric Cardiovascular Imaging Fellowship

Nationwide Children’s Hospital offers a one-year Pediatric Cardiothoracic Imaging Fellowship that focuses on the development and effective use of advanced imaging biomarkers for common cardiovascular, pulmonary and thoracic diseases in children.

The Pediatric Cardiothoracic Imaging Fellowship is a combined program with the Department of Pediatric Radiology, the Section of Pediatric Cardiology and the Department of Pediatrics at Nationwide Children’s Hospital. The full spectrum of pediatric cardiovascular MR and CT is performed, including neonatal imaging, complex 2-ventricle repair, all stages of single ventricle repair, aortopathy, cardiomyopathy, thrombosis, coronary anomalies, perfusion and viability. The full spectrum of childhood onset pulmonary and airway disease is also encountered, including dynamic airway CT for proximal airway compromise, cystic fibrosis, HRCT for CHILD, growth disorders, and fetal/neonatal surgical chest conditions. The fellowship also includes exposure to CMR and CT angiographic studies for vascular anomalies, portal hypertension, liver/renal transplant, venous obstruction, and systemic vasculitis, amongst others.

The fellows will have extensive hands-on experience in planning, performance, post-processing and interpretation of these exams, are active participants in management conferences and in the research program, and present at several major national and international meetings every year. The cardiothoracic reading room is located within the Pediatric Advanced Imaging Resource (PAIR), which includes 3D printing, virtual and augmented reality, and biomechanical flow modeling programs.

Nationwide Children’s Hospital recognizes fellowship training are challenging years of professional growth. We are committed to making these the best years of your medical education and to meeting your expectations for a high quality learning experience.

  • Over 1.2 million patient visits a year
  • One of the largest cardiovascular imaging programs in North America with 1000 CMR/MRA and 1500 CTA/dynamic airway studies a year
  • Combined program by the Department of Radiology and the Section of Pediatric Cardiology, Department of Pediatrics
  • Staffed by six attendings, two medical imaging scientists, four advanced imaging analysts and two cardiac imaging fellows (one each from cardiology and radiology)
  • Scanning on four different MR scanners with unique capabilities for cardiovascular imaging: multi-vendor, 1.5T and 3T experience.
  • Ferumoxytol based blood pool program, with whole body angiography for selected conditions
  • 4D flow based program for adult congenital heart disease
  • Pediatric Cardiovascular CT program based on volumetric and dynamic approach using a 320-detector scanner
  • Fellows are active participants in case management conferences
  • Family-friendly Midwest with excellent quality of life


The fellow’s training will include all aspects of pediatric cardiothoracic MRI and CT including familiarity with physics concepts, and specific MR and CT protocols required. Curriculum for cardiac imaging includes

  • Neonatal Imaging
  • Complex two ventricle repair
  • All stages of single ventricle repair
  • Aortopathy
  • Thrombosis and Embolism
  • Cardiomyopathy
  • Perfusion & Viability
  • Coronary Anomalies
  • Vascular Anomalies
  • Portal hypertension and liver transplant

Curriculum for thoracic and vascular imaging includes:

  • HRCT and Dynamic volumetric CTA
  • Childhood Interstitial Lung Disease
  • Proximal airway disorders, including Vascular Mediated Airway Compromise and tracheobronchomalacia
  • Fetal and neonatal surgical planning of thoracic lesions, incl. CPAM, CDH
  • MR lymphangiography
  • Vascular anomalies, including whole body assessment of syndromic and diffuse anomalies
  • Portal hypertension and liver transplantation
  • Renal transplant
  • Systemic vein thrombosis and vascular access planning

The fellow will be exposed to a broad range of topics in the subspecialty, not limited to but as outlined above. The fellow will spend most of their time in the cardiothoracic imaging section, but will participate in department wide conferences. Leading research and/or quality improvement projects is required.

Fellows will be required to attend:

  1. Departmental noon conference, daily
  2. Multidisciplinary Cardiac Case Management Conference Wednesdays and Fridays 7 a.m., weekly
  3. Journal Club, monthly

About Nationwide Children's Hospital

Welcome to the inspirational Nationwide Children’s Hospital! The Pediatric Cardiovascular Imaging Fellowship Program at Nationwide Children’s Hospital is one of the leading pediatric fellowship programs in central Ohio.

We are more than a hospital. We are one of America’s largest pediatric health care and research centers delivering care for more than one million patient visits each year. Families travel from around the nation and around the globe to access life-saving treatments – many unavailable anywhere else.

Nationwide Children's believes that no child should be refused necessary care and attention for lack of ability to pay. Upon this fundamental belief, Nationwide Children's is committed to providing the highest quality: patient care; advocacy for children and families and pediatric research; education of patients, families and future providers; and outstanding service to accommodate the needs of patients and families.

Research Opportunities

Diverse opportunities exist for participation in clinical, laboratory bench, educational and health systems research in pediatric cardiothoracic radiology and integrated clinical fields. Nationwide Children’s Hospital, The Abigail Wexner Research Institute at Nationwide Children’s Hospital and the Children’s Radiological Institute are recipients of both internal and external grant funding for clinical and laboratory bench research projects. Generous research funding is available for the interested fellow. Research pathways include sedation reduction, image phenotyping, 3D modeling/printing, virtual/augmented reality, parametric mapping in cardiomyopathy and biomechanical flow modeling. A dedicated research magnet with access to large animal imaging is available with active funded research programs on Tissue Engineered Vascular Graft development, fetal hemodynamic assessment, and interventional cardiac MR. A 0.55T low field magnet will be available end of 2023.
