Dr. Hugh McGregor is an Assistant Professor of Medical Imaging in the Vascular and Interventional Radiology division of the Department of Medical Imaging at the University of Arizona. Dr. McGregor received his medical degree from the Royal College of Surgeons in Ireland and completed his Diagnostic Radiology residency at the University of California, San Francisco. While a resident, Dr. McGregor received trainee research prizes at the annual Radiology Society of North America (RSNA) meetings (2015 and 2016) for his research focused gallbladder cryoablation, a minimally invasive treatment for gallbladder disease, and radiogenomics in dialysis arteriovenous fistulas (AVFs). Following his residency, Dr. McGregor completed a fellowship in Vascular and Interventional Radiology at UCSF, during which he received research funding from the RSNA to continue his work in AVFs and won the Society of Interventional Radiology (SIR) foundation's fellow research award. He then joined the faculty in the Vascular and Interventional Radiology division at UA.
Dr. McGregor's primary research interests include gallbladder cryoablation, a minimally invasive procedure to definitively treat gallbladder disease, endovascular endothelial cell sampling and genetic analysis in dialysis arteriovenous fistulas, and prostate artery embolization (PAE), a minimally invasive treatment for benign prostatic hyperplasia (BPH). His clinical and research interests also include lymphatic interventions, percutaneous liver, kidney, and lung ablations, prostate artery embolization, transarterial interventions for hepatocellular carcinoma and liver metastases, hepatobiliary interventions, venous disease, and inferior vena cava filters.
Dr. McGregor is a member of the Radiological Society of North America and the Society of Interventional Radiology.
