The purpose of this study is to evaluate the feasibility of the imaging method we developed to observe pulsatile motion of brain surface (brain surface motion imaging) for providing pre-surgical information about adhesion between meningioma and brain surface. Brain surface motion imaging is a method in which subtractions of images in systolic and diastolic phase of CSF/brain pulsatile motion are made. In the current study, prediction for brain/meningioma adhesion by brain surface motion imaging agreed with surgical findings in 83% of the cases. This imaging method seems to be feasible as providing presurgical information about brain/meningioma adhesion.
