Overview: The major shortcoming of image-guided navigational systems is the use of pre-surgically acquired image data, which does not account for intraoperative changes in brain morphology. The occurrence of these surgically induced volumetric deformations, or "brain shift", has been well established. Maximum measurements for surface and midline shifts were reported. There is no detailed analysis, however, of the changes occurring throughout the entire surgery. Intraoperative MRI provides a unique opportunity to obtain serial imaging data and characterize the time course of brain deformations during surgery. The vertically Brain shift is a continuous dynamic process, which evolves differently in distinct brain regions.
