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.

Neuroscience: Imaging - EEG, CT, PET scans and MRI

2008-09-14T03:41:16.531Z

Using the resources of the Brain Research Center at UCLA, this film illustrates the development of neuroscience, from its reliance on information from brain injuries and from autopsies, through to new insights discovered with electronic micro-scopes, EEG equipment, PET scans and MRI machines. These new means of exploring the brain have broadened and deepened the extent of research; each has its own uses and methodologies which are elaborated in the film. Throughout DISCOVERING THE HUMAN BRAIN: NEW PATHWAYS TO NEUROSCIENCE, examples of actual research that utilize current technology are presented, including a study on the role of mirror neurons in autism and the mapping of language areas of a patient prior to surgery on a brain tumor. Thus, this film provides students with an understanding of the methodology and power of current research in neuroscience.With Susan Bookheimer, Ph.D.

Surgical Robotics: neuroArm robot performs brain surgery - A world first

2008-08-22T17:40:28.826Z

A surgical team at the Foothills Medical Centre has successfully performed groundbreaking neurosurgery with a robot developed by a team at the University of Calgary Faculty of Medicine. A surgical robotic system developed by a team led by Dr. Garnette Sutherland, a Calgary Health Region neurosurgeon and professor of neurosurgery in the University of Calgary Faculty of Medicine. neuroArm is the world's first MRI-compatible surgical robot capable of both microsurgery and image guided biopsy. The surgical robotic system is controlled by a surgeon from a computer workstation, working in conjunction with intraoperative MR (magnetic resonance) imaging. Dr. Sutherland developed the intraoperative MRI machine with Winnipeg-based IMRIS Inc. The technology allows a high field MRI scanner to move in to the operating room on demand, providing imaging during the surgical procedure without compromising patient safety
