Study population: All patients with gliomas which are closed to motor area (including primary motor area, premotor area and supplementary area), treated by awake craniotomy and intraoperative brain mapping

Brief summary: This study was designed to collect a series of patients with gliomas which were involved in motor cortex to analyze difference accuracy of motor cortex localization between BOLD-fMRI and ZOOMit-fMRI.

Detailed description: Gliomas will lead motor dysfunction when they are involved in motor cortex. However, tumor resection also have risk to lead postoperatively motor function deficits if destroy patients' motor cortex when tumor removed. Hence, it is important for neurosurgeon to realize the situation of patients' motor cortex locations in order to determine personal operative protocol.

The blood oxygen level dependent fMRI (BOLD-fMRI) is a prevalent preoperative method to localization motor cortex. It shows motor relevant cortex by the change of blood oxygen level when patients cooperate to finish motor tasks. The advantage of BOLD-fMRI includes higher time and spatial resolution, higher sensitivity, non-invasive. However, its accuracy of localization has not been satisfactory because neurovascular uncoupling. The ZOOMit-fMRI is a novel technic which is evolved from conventional BOLD-fMRI to localize motor functional cortex.The advantage of ZOOMit-fMRI is smaller field of view (FOV) and higher spatial resolution comparing with BOLD-fMRI. That helps to reduce other region of brain interference and elevate accuracy of localizations.

In this study, the investigators plan to enroll 60 patients, whose gliomas are involved in motor cortex, to acquire their BOLD-fMRI and ZOOMit-fMRI data in order to analyze their difference in the accuracy of motor cortex localization.

Eligibility criteria: The inclusion criteria were as follows: 1) age ≥ 18 years; 2) no history of surgical treatment or radiotherapy; 3) no contraindication to MRI scanning; 4) agreeable to receive the fMRI scanning and awake craniotomy with DCS.

The exclusion criteria were as follows: 1) basing on the anatomic MRI, the distance from the tumor to the hand-knob area lower than 20 mm; 2) disable to finish the task of clenching fist during fMRI scanning.
