  • Use of CT and MR enterography to diagnose Crohn's disease and its complications — partnering with Mayo Clinic's IBD Clinic, the Society of Abdominal Radiology's Crohn's Disease-focused Panel, and the STAR Consortium — development of standardized and reproducible imaging criteria to diagnose and measure severity of enteric inflammation, Crohn's disease strictures; and perianal Crohn's disease, Crohn's disease response assessment and clinical trials using imaging endpoints
  • Photon-counting CT and radiation dose reduction in CT imaging — partnering with collaborators in Mayo Clinic's CT Clinical Innovation Center — development, validation, and integration into clinical practice of new and improved diagnostic imaging tests, which detect disease and improve patient care.
  • Colorectal cancer imaging — focusing on improved detection of hepatic metastases and peritoneal disease with CT imaging, and use of MRI for staging rectal cancer and evaluating pelvic recurrence
