目的:探讨功能核磁共振成像(fMRI)在脑中央区肿瘤手术中的应用价值。方法:11例脑中央区肿瘤患者,手术前行fMRI,明确脑皮质运动区与肿瘤的关系。结果:11例脑中央区肿瘤患者的脑皮质运动区均在fMRI上获得确定,11例手术切除的肿瘤患者均达显微镜下全切除。术后神经功能受损症状未加重。结论:fMRI图像对脑中央区肿瘤术前制定手术计划、评估手术风险,术中选择手术切除肿瘤的进路等非常有益。
Objective: To investigate the value of functional magnetic resonance imaging (fMRI) in tumor surgery in the central region of the brain. Methods: Eleven patients with central brain tumor were treated with fMRI before surgery to determine the relationship between the motor cortex and tumor. Results: The cerebral cortical motor areas of 11 patients with central brain tumor were all determined by fMRI. All 11 patients with resected tumors underwent total microsurgical resection. Postoperative neurological dysfunction symptoms did not increase. CONCLUSION: The fMRI images are of great benefit to the surgical planning of the tumor in the central brain area to evaluate the surgical risk and to choose the surgical approach to remove the tumor during operation.
