Radiology Fellowship

The Division of Diagnostic Imaging and Radiology offers: pediatric radiology fellowship training in an ACGME accredited program.

Since 1974, the Division of Diagnostic Imaging and Radiology has offered pediatric radiology fellowship training in a one year ACGME approved program. Training includes radiography, fluoroscopy, ultrasound, nuclear medicine, PET - CT, cardiovascular imaging, interventional radiology, computed tomography, magnetic resonance imaging and fetal imaging. Our mission is to train individuals who will provide high quality imaging care of children and who will serve as leaders and mentors in responsible practice, in education, in research and in advocacy. Optionally, we do provide a second year of specialized training in neuroradiology, nuclear medicine or cross sectional imaging.

Responsibilities traditionally include provision of excellence, timely and compassionate patient care, communication of issues of importance in a clear and effective manner, maintaining strong and effective working relationships, assurance that deficiencies will be identified and corrected, participation in departmental governance activities, understanding and providing appropriate risk management decisions.

Over 70 fellows have successfully graduated from this program. The Division performs over 130,000 examinations annually using state-of-the-art imaging equipment.

The Division performs diagnostic and minimally invasive procedures in a family environment with the lowest possible risk and the lowest achievable exposure to radiation. Many of our radiologists are national and international authorities in their fields. The Division employs over 160 radiologist, research faculty, physicist, technologist, nurses, and support staff. The Division has 17 board certified radiologist most of which hold certificated of added qualifications in pediatric radiology, neuroradiology, and vascular/interventional radiology. Our technologists are certified in specific modalities and are trained to work specifically with the pediatric population. The Division also includes licensed nursing staffs who are expert in pediatric conscience sedation.



The Department of Diagnostic Imaging and Radiology takes an active role in research at Children’s National. Fellows are encouraged to complete a research project during their year of training under the mentorship of one of the faculty. Numerous ongoing research projects are available to participate in.

The Radiology Research Laboratory is under the leadership of Catherine Limperopoulos PhD, with an emphasis on use and development of advanced MRI techniques and fetal imaging research.

The Biomedical Engineering group is led by Kevin Cleary, Ph.D. The research emphasis in this group includes minimally invasive / non-invasive approaches that can reduce painful procedures in children.

The radiology department is also involved in a multitude of collaborative programs within Children’s National that utilize imaging technologies and devices.

At the beginning of each academic year, the program director meets with the fellows as a group and each fellow as an individual. In these sessions, goals and objectives are set for each individual trainee. Goals are focused around achievement of diagnostic and treatment excellence, accomplishment in academic activity, preparation of graduate level seminar material, development of teaching skills, understanding of performance improvement, accreditation, business practices, and organization activities. The training program is tailored to the needs of each individual fellow with a considerable amount of flexibility under the supervision of the program director. Graduated levels of responsibility are provided. A close relationship between faculty mentors and fellows is the standard leading to collaboration in career development, academic activities, and general educational progress.

The training program lasts for a period of twelve months. This includes six months of general diagnostic radiology including fluoroscopy, in patient and out patient film interpretation, and cross sectional body imaging with clinical conference participation. There is one month of vacation. The remaining five months include rotations in nuclear medicine (1-2 months), neuroradiology (1-2 months), and interventional radiology (2 -8 weeks). Electives in fetal imaging, cardiac and musculoskeletal imaging are added as requested. Throughout the year, the trainee takes graduated night and weekend call, with increasing levels of responsibility in their rotations. A second year of training is available upon request. This involves further subspecialty training in neuroradiology, nuclear medicine, or cross sectional body imaging. These subspecialty rotations are accomplished under the direction of a faculty mentor.

Didactic lectures are given each morning. Interesting case conferences in neuro and body imaging are presented weekly. Journal clubs are presented monthly with fellows and residents in attendance. Combined case conferences with other specialties occur throughout the month including surgery, oncology, neurology, urology, fetal, neurosurgery, otolaryngology, genetics, gastroenterology, and orthopedics. At times the fellows are requested to present in pediatric professorial rounds and Surgery- Path conferences.

The fellows are expected to present at interesting case conferences and develop two didactic lectures during their training. Each fellow is responsible for presenting a basic radiology lecture on the chest to rotating medical students from George Washington University. Time is provided to complete a quality improvement project of the fellow’s choice.
