MR Imaging has been widely used in neurosurgery for guiding surgeons perform more accurate and less invasive surgery. Stereo-electroencephalography (SEEG) is considered as gold standard for epileptogenic zone (EZ) location with the depth electrode insertion procedure after craniotomy. Recently, with the development of surgical navigation, minimally invasive depth electrode insertion without craniotomy has been developed with many obvious advantages. The biggest challenge of the surgery is to avoid intracranial hemorrhage during the insertion. Accurate and fine imaging and reconstruction for cortical vessel can help surgeons perform the surgical planning to avoid the hemorrhage.
