Jonathan R. Dillman, MD, MSc

  • Associate Chief of Research, Department of Radiology
  • Medical Director, Imaging Research Center, Division of Radiology



I’ve always enjoyed working with children and find it immensely rewarding to have a lifelong impact on patients. Radiology is my clinical specialty with a particular interest in imaging the pediatric abdomen, inflammatory bowel diseases (including Crohn's disease) and chronic liver diseases. I frequently work collaboratively with multi-disciplinary teams, including gastroenterologists, hepatologists and cardiologists.

My research areas include novel quantitative imaging methods for diagnosis and staging severity of Crohn's disease and chronic liver diseases (such as fatty liver disease and autoimmune liver disease). My work aims to measure tissue and organ injury noninvasively and turn anatomic images into quantitative biomarkers.

I am honored to have received the Best Paper award from the Pediatric Radiology journal (2020), Best Gastrointestinal (GI) Scientific Presentation, Society of Abdominal Radiology (2020) and Department of Radiology Outstanding Clinician (2020). I have also received multiple grants, including funding from the Cincinnati Children's Foundation and the National Institutes of Health (NIH). I am board certified in Radiology (2008), with subspecialty certification in Pediatric Radiology (2011) by the American Board of Radiology.
