Dr. Ballard’s work centers on the development and application of advanced MRI techniques to characterize fistula anatomy, inflammatory activity, and disease severity, along with the evaluation of PET/MR approaches for assessing disease biology and treatment response in both perianal and ileocolic Crohn’s disease. He is a member of the Society of Abdominal Radiology’s Disease-Focused Panel on Inflammatory Bowel Disease and a participant in the TOpClass international consortium.
