Research Summary

Steven Hetts, MD, is an Associate Professor of Radiology in Residence at the University of California, San Francisco, and he is Chief of Neuroradiology at the San Francisco General Hospital where he has established a new clinical Interventional Neuroradiology service, providing cutting edge minimally invasive endovascular therapy. Dr. Hetts received his medical degree from Harvard Medical School in Boston, Massachusetts in 2000, and completed a residency in Diagnostic Radiology at UCSF, followed by a fellowship in Diagnostic Neuroradiology and Interventional Neuroradiology from UCSF.

Dr. Hetts is involved in translational research as Co-Director of the Interventional Radiology Laboratory at China Basin, including the conception, performance, and management of research projects translating basic science and engineering research into clinical applicability. One of his projects is Magnetic Catheter Navigation and Microinfarction Evaluation in the Brain and Heart. Dr. Hetts also implements many clinical research projects involving retrospective and prospective patient data. The main focus of his clinical research is endovascular therapy for cerebrovascular disease, spinal vascular disease, and neurooncology.
