Abstract: Objective To evaluate the functional features of motor function area in patients with meningioma by blood oxygenation level dependent functional magnetic resonance imaging (BOLD-fMRI).Methods fMRI were obtained from 10 patients who suffered from meningioma which was adjacent to the motor function cortex.Probabilistic independent component analysis method was used for data analysis.Preoperative and postoperative line Karnofsky Performance Scale (KPS)score was used to assess the patient’s condition.Re-sults Contralateral primary motor cortex and the supplementary motor cortex motor functions were observed in all the activation clusters,in which one side activation area compared with the contralateral activation zone was symmetrical in 6 cases,and significant shift in 4 cases.In 4 patients with the movement function activated,tumor extrusion function shift forward or backwardwith tensile deforma-tion were found.Conclusion BOLD-fMRI imaging technology can effectively locate motor functional area for patients with meningi-oma,which can provide preoperative surgical planning.
