Conditions

Patients with preoperatively suspected supratentorial meningiomas on imaging, whose lesions are adjacent to the precentral gyrus

Interventions

Experimental group:In addition to the standard clinical management pathway, preoperative motor mapping was performed using helium-free MEG. During surgery, the OPM-MEG motor mapping results were integ
Control Group:Prior to surgery, participants underwent relevant examinations in accordance with standard clinical protocols (which may include fMRI, DTI, etc.). During surgery, routine imaging data we

Inclusion criteria

Inclusion criteria: (1) Aged 18–75 years; gender is not a factor; (2) Patients with a presumptive preoperative imaging diagnosis of supratentorial meningioma who are scheduled to undergo neurosurgical treatment; (3) The tumor’s area of abnormal signal on MRI contrast-enhanced imaging covers or compresses the precentral gyrus or paracentral lobule; (4) Patients who are able to understand and cooperate with this study and have signed an informed consent form.

Exclusion criteria

Exclusion criteria: (1) Patients with preoperative limb muscle strength below Grade 3 on the MRC muscle strength scale; (2) Patients with incomplete clinical data; (3) Patients with claustrophobia; (4) Patients unable to lie supine for more than 30 minutes; (5) Patients with ferromagnetic objects implanted above the costal margin of the thoracic cavity (internal foreign bodies, implanted pacemakers, cardiac resynchronization devices/defibrillators, infusion pumps, and/or nerve stimulators); (6) Patients with a confirmed diagnosis of psychiatric or psychological disorders, or those with uncontrolled psychiatric symptoms, who are unable to understand and cooperate with the study; (7) Patients with marked increased intracranial pressure, cerebral herniation, unstable vital signs, or meningioma suspected to be associated with tumor-related stroke; (8) Other conditions deemed by the investigator to render a patient ineligible for this study.
