DSI in brain tumor
The superimposed neuronal fiber structures are difficult to be resolved by current neuroimaging modalities. Here we demonstrate 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 us to reformat 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, we 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.

2D/3D Medical Animation: TBI - Traumatic Brain Injury Part 2
Traumatic Brain Injury - TBI
In correlation with some of the nation's leading medical experts and trial attorneys who specialize in "mild traumatic brain injury (mild TBI)", MediVisuals has developed an interactive animated software that demonstrates how traumatic brain injuries can occur without a significant blow to the head and without being evidenced on imaging studies.
Animated sequences based upon crash tests demonstrate the movements associated with a "typical" sudden deceleration incident. Multiple other animation sequences explain the involved anatomy and show the soft, fragile brain impacting on the hard and uneven inner surface of the skull. The sequences demonstrate how multiple axonal injuries can occur from the shearing forces (both with and without hemorrhage and both with and without positive findings on imaging studies). An additional animation sequence demonstrates how the combined deceleration and rotational forces result in axonal injury in the corpus callosum.
