Medical College of Wisconsin Neuroradiology Fellowship Program

Welcome to the Section of Neuroradiology at the Medical College of Wisconsin at Milwaukee! The Neuroradiology Fellowship Program at MCW-Milwaukee is ACGME-accredited and offers well-rounded training in day-to-day care/functions as well as advanced Neuroradiology. The program emphasizes a deeper level of understanding of neuroscience and neuroradiology through structured didactic lectures and interdisciplinary conferences. Trainees also get exposure to advanced Neuroradiology by participating in pre-surgical functional mapping of eloquent areas of the brain, and by participating in volumetric analysis of the brain in patients with cognitive impairment and dementia. The program believes in an engaging environment and strongly believes in team culture. Follow the program on twitter @MCWNeurorad. For a fun Neuroradiology quiz follow our weekly quiz #MCWNeuroradBTW on Twitter.

Currently Accepting Applications for Fellowship Starting 2024-2025



The Neuroradiology Fellowship with the Medical College of Wisconsin Affiliated Hospitals (MCWAH) is a one-year, ACGME-accredited program that offers comprehensive training in the translation of advanced neuroimaging techniques to the everyday practice of neuroradiology.

  • Exceptional Clinical Application Exposure - This program is highly respected as one of the country’s leaders in the clinical application of fMRI, DTI, MR perfusion, Radial diffusivity, ASL, Segmental brain volume analysis, and Simultaneous integration of the techniques for regional and whole brain analysis.
  • Cutting Edge Technologies - Fellows have access to commercial and proprietary cutting edge technologies from close ties to industry leaders and in-house biomedical research.

  • Experienced Faculty Dedicated to Teaching

  • Diverse Clinical Pathology – Technology and training combined with the diverse clinical pathology of a major metropolitan area prepares fellows to function at the forefront of any academic or private practice environment.

Our fellowship is carefully designed with a formal education structure:

  • Elevated Experience – Emphasis on a deeper level of understanding of neuroradiology that exceeds the residency experience and what can be gleaned from mere quantitative case exposure.
  • Active Learning Methods - The department is proactive in faculty development of modern educational techniques.
Program Leadership

Program Leadership

Three individuals guide the neuroradiology fellowship:

  • Andrew Klein, MD, Fellowship Program Director, Section Chief of Neuroradiology
  • Darren O'Neill, MD, Associate Fellowship Director, emphasis on MRI
  • David Smullen, MD, Associate Fellowship Director, emphasis on emergency neuroradiology

Ten additional neuroradiologists contribute to fellowship training:

  • Ryan Beck, MD
  • Zaneta Dymon, DO
  • Sonia Gill, MD, emphasis on head and neck imaging
  • John Hamer, MD
  • Christopher Kleefisch, MD
  • Vincent Mathews, MD, department chair and board of trustee member of the American Board of Radiology
  • Michelle Michel, MD, past president of the American Society of Head and Neck Radiology
  • David Polinger-Hyman, MD
  • David Rockwell, MD, emphasis on emergency neuroradiology
  • James Strottmann, MD, emphasis on CT perfusion
Clinical Experience

Clinical Experience

The Fellowship is designed to provide extensive clinical experience in interpretation of MR spectroscopy, fMRI, diffusion tensor imaging and tractography, perfusion/blood volume imaging, CT/PET imaging, neuro-interventional procedures, dementia and biomarker imaging, in addition to conventional neuroradiology imaging studies.

Fellows receive ten weeks of training in each of these areas:

  • Brain and Spine MR
  • Brain and Spine CT
  • Vascular Neuroradiology & Myelography/Degenerative Spine Imaging

The fellows' rotation schedule is constructed in an ongoing cycle throughout the fellowship year:

  • Brain, Head and Neck, Spine MR, Spine CT, and Vascular Neuroradiology and Myelography/Degenerative Spine Imaging with a provision for academic time.

The design of the reading room environment and PACS system forces inter-modality imaging correlation, providing even greater exposure to cases. Each fellow has a four-week rotation of Pediatric Neuroradiology at Children’s Hospital of Wisconsin. Fellows also complete a six-week rotation of Adult Interventional Neuroradiology at Froedtert, to gain experience in catheter-based angiography.

The Froedtert Neurosciences Research Center provides a major infusion of patients with challenging diagnostic problems. Weekly neuroscience conferences bring together neuroradiologists, neurologists, neurosurgeons, neuropathologists and radiation oncologists to discuss various aspects of neuro diagnosis and therapy.

State-of-the-art Equipment and Technology

Imaging facilities include:

  • Six state-of-the-art Helical CT
  • Six MR scanners on site, with access to an experimental 1.5 and 3.0T imager
  • Three up-to-date Digital Angiography Suites, and a Biplane Neuroangiography Suite with 3D Rotational Angiography
  • State-of-the-art GE as well as Siemens CT (Somatom Plus) and MR (1.5T)

Research and Teaching Opportunities

Research and Teaching Opportunities

Research Opportunities
Fellows have significant opportunities to develop research project(s) in functional imaging, neuropathology, and/or neuroanatomy under the guidance of faculty with diverse research interests. Each fellow is mentored by one or more of the neuroradiology faculty, which provides a wealth of research and publication experience. The Neuroradiology Section overall submits between 10 and 20 manuscripts and/or abstracts per academic year, frequently receiving acceptances and awards.

Teaching Opportunities
Fellows have responsibility for teaching both radiology and non-radiology residents image protocoling, interpretation, and report generation. The fellows review special procedures, and CT and MR examinations with residents and medical students prior to staff read-out sessions. Fellows will also explain imaging procedures to medical students rotating through the service.

Additionally, each fellow is provided opportunities to present case conferences for residents and medical students throughout the fellowship year.

Bi-weekly Lecture Series Dedicated to Fellows

Bi-weekly Lecture Series Dedicated to Fellows

Topics include:

  • Advanced imaging
  • Basic neuroscience and targeted neuroradiologic lectures that explore brain structure and function
  • Brain cutting sessions with the neuropathologist
  • Unique dedicated neuroradiologic M&M conferences that explore the sources and reasons for errors.

Neuroradiologic Teaching File - Fellows are contributors to a teaching file database promoting active learning and providing an extensive learning resource.

MCW Neuroradiology Fellowship: from our Fellows

Our current Fellows talking about the program and what they think of living in Milwaukee.

Fun part of being at MCW Neuroradiology

At MCW Neuroradiology we take wellness to a whole new level, the level of fun! We believe in making work and education fun. The unique disco ball (yes!) in our reading room is turned on when our reading list goes to zero. We run a weekly Neuroradiology quiz called the Brain Teaser of the Week (Find our quiz on Twitter #MCWNeuroradBTW), the winners of which are declared the NeuroTriWizards (NTWs) for the year. This fun activity gives us the chance to celebrate and we are constantly looking for new restaurants for our award ceremonies, which we finance with our special NeuroFunFund. We also have a Harry Potter themed Roentgen School of Dark Arts where trainees participate with team spirit in educational activities.
