TBI:Traumatic Brain Injury...How it affects the brain - Dr. James Kelly

2009-09-11T11:44:46.166Z

BrainLine.org interview with Dr. James Kelly, Professor of Neurosurgery and Physical Medicine and Rehabilitation at the University of Colorado Denver School of Medicine. Dr Kelly has recently accepted appointment as the founding Director of the National Intrepid Center for Excellence (http://medtechiq.ning.com/video/2140535:Video:816), which is being constructed for the U.S. Military Health System in Bethesda, Maryland, on the campus of the National Naval Medical Center and Uniformed University of Health Sciences, and future site of the Walter Reed National Military Medical Center. Dr. Kelly specializes in all aspects of traumatic brain injury research and clinical care. His scientific publications and editorials have appeared in numerous medical journals, and he is invited to speak on a variety of neurological topics across the United States and abroad. Among countless other affiliations, positions, and publications, he was lead author of the Colorado and American Academy of Neurology Guidelines for the Management of Sports Concussion, and a co-author of the Standardized Assessment of Concussion (SAC), which is the most widely used sideline mental status test in sports.

Imaging: IBM - Mayo Clinic Establish Medical Imaging Research Center

2008-11-17T15:17:40.723Z

Mayo Clinic and IBM are creating a collaborative research facility aimed at advancing medical imaging technologies to improve the quality of patient care. The Medical Imaging Informatics Innovation Center (MI3C) is an extension of a 2007 Mayo-IBM announcement, the results of which have given physicians the ability to register medical images up to 50-times quicker and provide critical diagnosis, such as the growth or shrinkage of tumors, in seconds instead of hours.

Imaging: New generation neuroimaging - 3D multi-modality hybrid imaging

2008-10-24T10:55:50.684Z

The superimposed neuronal fiber structures are difficult to be resolved by current neuroimaging modalities. Here at the National Taiwan Univeristy Hospital 3T MRI Laboratory, is demonstrated a novel technology called diffusion spectrum imaging (DSI) to disentangle the complicated fiber structures. The images are acquired on a 3-Tesla MRI machine, including 3D high resolution T1-weighted images and DSI. 3D high resolution T1-weighted images allow reformating the images into different orientations, and is helpful in assessment of tumor extension. The MRI images are acquired from a patient with a brain tumor. In T1-weighted images, the tumor contour is ontlined and pseudocolored in yellow. Using DSI-reconstructed tractography, one can evaluate the relationship between the tumor and white matter tracts. The tractography shows three different tracts: corticospinal tract (blue one), corpus callosum (red one), and cingulum (green one). As you can see, the middle part of corpus callosum is totally interrupted by the tumor and the cingulum is pushed into the contralateral side. The corticospinal tract is not effected. The DSI tractography merged with the tumor contour explains the patient's neurological symptoms and helps neurosurgeons in presurgical planning.

Imaging: Human Brain Magnetic Resonance / Diffusion Tensor Imaging

2008-10-05T21:11:42.784Z

Courtesy of Brain dataset from Gordon Kindlmann at the Scientific Computing and Imaging Institute, University of Utah, and Andrew Alexander, W. M. Keck Laboratory for Functional Brain Imaging and Behavior, University of Wisconsin-Madison this is a demonstration of DT-MRI (Diffusion Tensor - Magnetic Resonance Imaging). An advanced medical imaging technique that allows in vivo measuring of location and orientation of nerve fibers in human brain. Water molecules move (diffuse) along nerve fibers, and the diffusion anisotropy can be measured and displayed.

Functional MRI method measures blood oxygen level and thus neuronal activity of the brain. By combining both techniques neural bundles involved in certain activities can be visualized.
