William P. Dillon, MD


Dr. William Dillon is an expert in neuroradiology of the brain, head and neck. He has a special interest in head and neck radiology, magnetic resonance imaging (MRI) of cerebral vascular malformations, MRI and spectroscopy of brain tumors and minimally invasive methods for diagnosing and treating spine disorders.

Dillon earmed an undergraduate degree at the University of California, Los Angeles. He completed a residency in radiology at the University of Utah, followed by a fellowship in neuroradiolgy at the University of California, San Francisco in 1982. He was appointed section chief of neuroradiology at UCSF in 1992, where he also is vice chair for research in the radiology department. Dillon is past president of the American Society of Neuroradiology and the American Society of Head and Neck Radiology. He has written over 200 peer reviewed articles as well as several textbooks.
