Research Summary

Benjamin M. Yeh, MD, is a Professor in the Abdominal Imaging Section in the Department of Radiology at the University of California, San Francisco. He received his medical degree from Duke University School of Medicine, and completed his residency in diagnostic radiology and fellowship in abdominal imaging at the University of California, San Francisco.

Dr. Yeh directs the Contrast and CT Research lab at UCSF which explores novel contrast-enhanced imaging techniques for CT, dual energy CT, and MR imaging. Ongoing projects include the development and testing of novel contrast materials, bowel imaging, fibrosis imaging, assessment of contrast material distribution in healthy and diseased tissues, and oncologic imaging. His research group is recognized for mentoring medical students, residents, and fellows, including five Howard Hughes Medical Student research fellows, and visiting faculty.
