Ryan Kohlbrenner, MD

Assistant Professor
Asst. Prof. Clinical Radiology

Biography

Ryan Kohlbrenner, MD, is an Assistant Professor in the Interventional Radiology subspecialty in the Department of Radiology and Biomedical Imaging at the University of California, San Francisco. He received his medical degree from the University of Chicago Pritzker School of Medicine, Illinois, and he completed a one-year internship at Washington University, St. Louis/Barnes - Jewish Hospital, Missouri. Dr. Kohlbrenner completed his four-year diagnostic radiology residency at the University of California, San Francisco and served as chief resident in his senior year. He subsequently completed his Interventional Radiology fellowship at University of California, San Francisco.

Primary research interests of Dr. Kohlbrenner include computer-aided diagnosis, image processing, and radiation dose reduction for patients undergoing interventional procedures. His clinical interests include percutaneous liver and kidney ablations, prostate artery embolization for benign prostatic hyperplasia (BPH), and transarterial interventions for hepatocellular carcinoma and liver metastases.

Inquiries about ablative therapies and prostate artery embolization (experimental procedure) can be made to Ryan.Kohlbrenner@ucsf.edu.
