Rate My Professor Hugh McGregor

Hugh McGregor, MD, is an Associate Professor in the Department of Radiology at the University of Washington, where he serves as the Section Chief of Interventional Radiology. He earned his medical degree from the Royal College of Surgeons in Ireland in 2011, completed a surgical internship at the University of Hawaii in Honolulu in 2012, a residency in Diagnostic Radiology at the University of California, San Francisco in 2016, and a fellowship in Vascular and Interventional Radiology at UCSF in 2017. Prior to joining the University of Washington, Dr. McGregor was an Associate Professor in the Department of Radiology at the University of Arizona, where he also served as Associate Director of the Interventional Radiology Residency Program.

Dr. McGregor's clinical interests include prostate artery embolization for benign prostatic hyperplasia, interventional oncology such as percutaneous liver, kidney, bone, and lung ablations and Y90 radioembolization, lymphatic interventions, treatment of pulmonary embolism, management of inferior vena cava filters, and gallbladder cryoablation. His research specializations encompass gallbladder cryoablation as a minimally invasive treatment for gallbladder disease, endovascular endothelial cell sampling and genetic analysis in dialysis arteriovenous fistulas, prostate artery embolization, and trans-arterial interventions for hepatocellular carcinoma and liver metastases. He received trainee research prizes from the Radiological Society of North America in 2015 and 2016 for work on gallbladder cryoablation and radiogenomics in arteriovenous fistulas, RSNA research funding during his fellowship, and the Society of Interventional Radiology Foundation’s fellow research award. Notable publications include "Gallbladder Cryoablation for Calculous Cholecystitis Initially Treated with Percutaneous Drainage: A Prospective Trial in High-Risk Patients" (Journal of Vascular and Interventional Radiology, 2025), "Percutaneous Radiofrequency Ablation to Occlude the Thoracic Duct: Preclinical Studies in Swine for a Potential Alternative to Embolization" (Journal of Vascular and Interventional Radiology, 2022), "Pulmonary Vascular Interventions" (Radiologic Clinics of North America, 2025), and "Prior Ablation and Progression of Disease Correlate with Higher Tumor-to-Normal Liver 99mTc-MAA Uptake Ratio in Hepatocellular Carcinoma" (Abdominal Radiology, 2023). Dr. McGregor performed the first gallbladder ablation and the first kidney radioembolization procedure at the University of Washington. He is a member of the Radiological Society of North America and the Society of Interventional Radiology.
