Nicholas Fidelman, MD

Assistant Professor
Asst. Prof of Clin Radiology

Biography

Nicholas Fidelman, MD, is an Assistant Professor of Clinical Radiology at the University of California, San Francisco and UCSF Mount Zion. Dr. Fidelman received his medical degree from UCSF in 2002, and completed his residency in Diagnostic Radiology from UCSF in 2007, followed by a fellowship in Interventional Radiology from UCSF in 2008.

Dr. Fidelman’s research interest is focused on determining the outcomes of many commonly performed procedures in Interventional Radiology, and on improving the safety and efficacy of imaging-guided interventions. One of Dr. Fidelman’s interventional oncology projects currently focuses on Yttrium-90 liver radioembolization in patients with primary and secondary liver malignancies and on safety of chemoembolization in patients with primary liver cancer and marginal liver reserve.

Other ongoing projects are focused on biliary procedures, elucidating the role of percutaneous cholangiography and biliary drainage in management of patients with biliary complications after living-related liver transplantation, and determining optimal treatment for patients with malignant hilar bile duct obstruction. Dr. Fidelman has over 30 research publications, including comparative and evaluation studies.
