| 摘 要： | 目的 探讨弥散张量成像(DTI)在脑深部肿瘤术前评估和手术设计中的作用.方法 回顾性分析20例脑深部肿瘤病人的临床资料,利用各向异性分数(FA)图和纤维示踪图(DTT),观察白质纤维束结构、走行及其与肿瘤的毗邻关系,测量病侧白质纤维束及其对应健侧白质纤维束的FA值、弥散系数(ADC)值.结果 白质纤维束单纯推移5例,单纯破坏7例,推移并破坏8例.单纯破坏、推移并破坏者.其病侧与健侧FA值、ADC值比较均有显著差异(P <0.05);而单纯推移者,其病侧与健侧队值、ADC值比较无显著差异(P >0.05).肿瘤全切除15例,次全切除3例,部分切除2例.12例随访6个月-2年,平均1年.正常工作、学习8例,生活自理但未参加工作3例,死亡1例.结论 DTI有助于准确判断肿瘤与周围白质纤维束的毗邻关系,对脑深部肿瘤术前评估和手术设计有重要指导意义.

| Abstract: | Objective To explore the role of diffusion tensor imaging(DTI) in the preoperative assessment and surgical planning of deep-seated brain tumor.Methods Clinical data of 20 patients with deep-seated brain tumors were analyzed retrospectively.The fractional anisotropy(FA) maps and diffusion tensor tractography(DTT) were used to evaluate the structure and course of white matter(WM) fiber tracts and the adjacent relationship between the WM and tumors.The values of apparent diffusion coefficient(ADC) and FA were ... |
