Dr. Clifford Weiss is a Professor of Radiology and Radiological Science. He also holds appointments in Surgery and Biomedical Engineering. Additionally, he serves as Medical Director of the Johns Hopkins Center for Bioengineering Innovation and Design (CBID), the Director of the Johns Hopkins HHT Center of Excellence as well as Director of the Johns Hopkins Vascular Anomalies Center. Dr. Weiss' clinical focus lies in vascular and interventional radiology with a particular focus on the diagnosis and treatment of vascular malformations. This includes venous and lymphatic malformations, arteriovenous malformations, pulmonary arteriovenous malformations and Hereditary Hemorrhagic Telangiectasia (HHT) and varicoceles. Dr. Weiss also is a pioneer in the use of MRI for interventional guidance (iMRI), especially for the treatment of vascular malformations. Dr. Weiss' research focuses primarily on the preclinical and clinical development of Bariatric Embolization, a new endovascular procedure designed to help fight obesity, and on the development of new embolic therapies and devices. Dr. Weiss is the Deputy Editor of Interventional Content for the journal Radiology. Dr. Weiss received his B.A. from Dartmouth College in 1995, his M.D. from the Johns Hopkins University School of Medicine in 2001. He completed an internship in internal medicine on the Osler Service in 2002, his residency in Diagnostic Radiology in 2007, and a Fellowship in Vascular and Interventional radiology in 2008, all at The Johns Hopkins Hospital. He is a Fellow both of the Society of Interventional Radiology (SIR) and of Cardiovascular and Interventional Radiological Society of Europe (CIRSE). Dr. Weiss is highly rated in 7 conditions, according to our data. His top areas of expertise are Pulmonary Arteriovenous Malformation (PAVM), Pulmonary Arteriovenous Fistula, Arteriovenous Malformation, Liver Embolization, and Embolectomy.

Dr. Kelvin K. Hong is an Associate Professor and Executive Vice Chair of Radiology within the Johns Hopkins Department of Radiology. A specialist in interventional and vascular radiology, Dr. Hong serves as the Medical Director of the Johns Hopkins Interventional Radiology Center. Dr. Hong earned his medical degree from South Africa’s University Of Witwatersrand Medical School in Parktown. He completed a radiology residency at Parktown West’s College of Medicine/Radiology, as well as a cardiovascular/interventional radiology fellowship and diagnostic radiology residency at The Johns Hopkins Hospital. His areas of clinical expertise include bone, liver and soft-tissue tumors; chronic total occlusions; claudication; deep venous thrombosis; lung, esophageal and kidney cancer; peripheral arterial/vascular disease; renal artery/vascular disease; uterine fibroid tumors; varicocele; and vascular malformations and venous thromboembolism. Dr. Hong performs procedures that include radiofrequency ablation for lung, liver, kidney and bone lesions; transcatheter arterial chemoembolization for liver cancer; lower-extremity angioplasty and stenting; visceral angioplasty and stenting; embolization of uterine fibroid tumors; cryoablation for pain control; and percutaneous laser ablation of varicose veins. Dr. Hong served as editor for the book Percutaneous Tumor Ablation and contributed to Interventional Oncology: Principles and Practice. Dr. Hong is highly rated in 13 conditions, according to our data. His top areas of expertise are Fibrolamellar Carcinoma, Bile Duct Obstruction, Neuroendocrine Tumor, Liver Embolization, and Pancreaticoduodenectomy.

Dr. Philippe Gailloud is an Associate Professor in the Johns Hopkins Medicine Department of Radiology and Radiological Science, Department of Neurology and Department of Neurological Surgery. Among his main areas of specialization are the development of interventional techniques, the percutaneous treatment of brain, spinal cord, and spine lesions, and the anatomy and embryology of the cerebral vasculature. Besides the diagnosis and treatment of cerebrovascular diseases in adult patients, Dr. Gailloud also focuses on the management of neurovascular disorders in children. Dr. Gailloud received his medical degree from the University of Geneva, Switzerland, in 1991, and completed his residency in diagnostic and interventional radiology at Geneva University Hospital in 1998. He completed a research fellowship in morphology at the University of Geneva in 1994, and clinical fellowships in diagnostic and interventional neuroradiology at Johns Hopkins. He joined the Johns Hopkins faculty in 2000. Dr. Gailloud has published more than 250 peer-reviewed scientific publications and 25 book chapters on a wide range of topics related to diagnostic and interventional neuroradiology.
