Graduate Medical Education - Residencies and Fellowships



  • Program Administrator: 619-532-6755

    The Body Imaging Fellowship at Naval Medical Center, San Diego is a clinical fellowship focused primarily on gastrointestinal and urogenital imaging using cross-sectional and 3-D CT, MRI, US, and fluoroscopy at the Naval Medical Center, San Diego. Through a formal collaborative agreement with University of California, San Diego Body Imaging Fellowship Program, the fellow has the option of expanded learning opportunities at that facility. Three elective months are available to focus on particular interests in body imaging, breast imaging, or interventional skills. The fellow is expected to participate in tumor boards, journal club, case conferences, didactic conferences, and multidisciplinary conferences. The fellow also participates in graduate medical education for rotating medical students, interns, and residents. The department has state-of-the-art CT scanners, four 3T MRI magnets, PET-CT, and 2D/3D ultrasound units. The Radiology-Oncology Division is part of the Radiology Department.

She immediately transitioned into the Body Imaging Fellowship Program training both at NMCSD and University of California, San Diego until 2008. During fellowship CDR Taysom acquired specialized training in high-risk obstetric ultrasound and returned to NMCSD as the sole specialist in this area. With that unique experience she speaks at national graduate medical education courses and participates in research in fetal imaging. CDR Taysom currently serves as the Program Director for the Body Imaging Fellowship and as the Academic Chief of Ultrasound at Naval Medical Center, San Diego. She also serves as an Assistant Professor of Medicine for the Uniformed Services University of Health Sciences with a particular focus on instructing medical students in bedside ultrasound skills.

    CDR Robert Marks is the Associate Body Imaging Fellowship Director. He graduated with a BA in Biochemistry with honors from the University of Colorado at Boulder in 1998. After working as a chemist for one year, he began medical school at the Uniformed Services University of the Health Sciences, graduating in 2003. After graduation, CDR Marks entered Pediatrics Internship at the National Capital Consortium in Washington, DC. After internship, he trained at the Naval Aviation Medical Institute in Pensacola, FL and became a U.S. Naval Flight Surgeon where he was assigned to Carrier Air Wing NINE at Naval Air Station, Coronado, CA from 2005 through 2007. After making two deployments, CDR Marks entered into the Radiology Residency Program at Naval Medical Center Portsmouth, VA in 2007. After completion of residency in 2011, CDR Marks immediately entered fellowship training in Body Imaging at Naval Medical Center, San Diego, training at NMCSD and the University of California, San Diego. During fellowship, CDR Marks focused on gastrointestinal and genitourinary MRI, specializing in liver, renal, pelvic, and fetal MRI. After fellowship, CDR Marks remained on faculty at NMCSD. Currently, CDR Marks serves on the ACR Liver Imaging Reporting and Data System (LI-RADS) committee and the Society of Abdominal Radiology Disease Focus Panel on Hepatocellular Carcinoma Diagnosis. He is the Chief of Abdominal Imaging and is the Head of Research and Academics in the Department of Radiology at NMCSD, and is an Assistant Professor of Radiology at the Uniformed Services University of the Health Sciences, with a focus on mentoring medical students, residents, and fellows in radiology research.

    NMCSD faculty include 5 body imaging fellowship trained specialists, in addition to 30 subspecialists in cardiovascular, musculoskeletal, pediatric, neurology, nuclear medicine, interventional and breast imaging.
