【摘要】：目的采用磁共振成像中的DTI技术及Klingler解剖技术，对人体脑白质解剖结构进行相关研究，为脑部病变的临床诊断、准确定位提供参照资料。方法 1.10例成人尸体颅脑标本采用Klingle解剖技术，对脑白质进行逐层分离，，观察并进行数据测量。2.对10名健康志愿者采用MRI-DTI成像技术进行脑白质纤维束成像，同时应用扩散张量纤维束示踪成像（DTT）方法对感兴趣区进行重建。结果 1.采用Klingler解剖技术可清晰显示脑内、外囊、弓状束、钩状束、额枕下束、视辐射等脑白质纤维束及屏状核的结构及位置。2.采用磁共振成像中的DTI技术能够直观而清晰的显示主要脑白质纤维束。结论 1.运用Klingler解剖技术及MRI DTI成像技术可直观、清晰显示脑白质主要纤维束的结构及位置。2.脑白质基本结构相同，但部分脑白质的大小、形态却存在个体性差异。3.通过DTI技术可以较好的对脑白质进行临床诊断及准确定位。
[Abstract]:PurposeIn order to provide reference for clinical diagnosis and accurate localization of brain lesions, DTI and Klingler techniques were used to study the anatomy of the white matter of human brain.Method1.10 adult cadaveric brain specimens were dissected layer by layer by Klingle technique, observed and measured.The white matter fiber bundle imaging was performed in 10 healthy volunteers, and diffusion Zhang Liang tracer imaging was used to reconstruct the area of interest.Result1.The structure and location of white matter fiber bundle and palmatoid nucleus in brain, external capsule, arcuate bundle, hook bundle, frontal suboccipital bundle, visual radiation and so on can be clearly displayed by Klingler anatomical technique.The main white matter fiber bundle can be visualized and clearly displayed by DTI technique in magnetic resonance imaging.Conclusion1.Klingler anatomical technique and MRI DTI imaging technique can be used to visualize the structure and location of the main fibrous bundles in the white matter.The basic structure of white matter is the same, but the size and morphology of some white matter are different. 3. 3.The clinical diagnosis and accurate localization of white matter can be made by DTI.
