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:6例脑中央区肿瘤患者,手术前行fMRI,明确脑皮质感觉、运动区与肿瘤的关系。结果:6例脑中央区肿瘤患者的脑皮质感觉、运动区均在fMRI上获得确定。5例手术切除的肿瘤患者均达显微镜下全切除。1例额顶叶胶质瘤行立体定向穿刺活检明确病变性质后行放射治疗。术后神经功能受损症状未加重。结论:功能MR(fMR)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: Six patients with central brain tumor who underwent fMRI before surgery to determine the relationship between cerebral cortex sensation, motor area and tumor. Results: The cerebral cortex sensory and motor areas of 6 patients with central brain tumor were all determined on fMRI. Five patients with surgically resected tumors underwent total microscopic resection. One case of frontal glioma underwent stereotactic biopsy to confirm the nature of the lesion before radiotherapy. Postoperative neurological dysfunction symptoms did not increase. CONCLUSION: Functional MRI (fMR) images are of great benefit to the surgical planning of the tumor in the central region of the brain, to assess the surgical risk, and to choose the surgical approach to remove the tumor during surgery.
