Dr. David M. Yousem is the Vice Chairman of Radiology, Director of Neuroradiology and Professor in the Johns Hopkins Medicine Department of Radiology and Radiological Science. He specializes in neuroimaging.

Dr. Yousem received his B.S. and M.D. degrees at the University of Michigan. He completed a radiology residency at Johns Hopkins and a two-year fellowship in neuroradiology at the University of Pennsylvania. He received his M.B.A. at Johns Hopkins University in 2003.

Dr. Yousem's expertise spans the full gamut of neuroradiology techniques including computed tomography (CT), magnetic resonance imaging (MRI), angiography, myelography, CT guided aspirations and biopsies, functional MRI, diffusion and perfusion imaging, MR/CT angiography, and 3-D reconstructions. He is a noted authority on disorders of the brain, spine, head and neck, olfaction, cranial neuropathies and neurodegeneration.

Dr. Yousem has authored or edited three books—Neuroradiology: THE REQUISITES, Head and Neck Case Review, and Radiology Business Practice: How to Succeed, all published by Mosby/Elsevier—and has edited four journal issues. He has published over 200 articles in peer-reviewed journals and over 50 chapters in books and has lectured on five continents.

He served as President of the American Society of Neuroradiology in 2008-2009 and the Treasurer of the World Federation of Neuroradiological Societies from 2011 to present. He sits on many of national radiological societies committees.

Dr. Yousem has completed two marathons (best time: 3 hours, 54 minutes), a half Ironman, and a full Ironman (2.5-mile swim followed by 112-mile bike ride and then a 26-mile run) competition.

    e-Radiology Learning - Neuroradiology Pearls and Pitfalls (1 of 4)

    Dr. Yousem discusses the importance of diagnosing thiamine deficiency before the patient develops an encephalopathy.

    e-Radiology Learning - Neuroradiology Pearls and Pitfalls (2 of 4)

    Dr. Yousem explains that when we see increased signal intensity bilaterally in the posterior column of the spinal cord, there is a limited differential diagnosis.

    e-Radiology Learning - Neuroradiology Pearls and Pitfalls (3 of 4)

    Dr. Yousem discusses the importance of diagnosing thiamine deficiency before the patient develops an encephalopathy.

    e-Radiology Learning - Neuroradiology Pearls and Pitfalls (4 of 4)

    Description: In this study we find abnormal signal intensity, which is present both in the anterior portions of the brain bilaterally and symmetrically, as well as in the posterior portions of the brain. The pons is involved as well as the cerebellum. The post-contrast T1 weighted scans demonstrate little enhancement. Dr. Yousem will review the T2 weighted series and the diffusion images with you and discuss the differential diagnosis.
