Diffusion tensor imaging (DTI) is an advanced MR technique that provides qualitative and quantitative information about the micro-architecture of white matter. DTI and its post-processing tool fiber tractography (FT) have been increasingly used in the last decade to investigate the microstructural neuroarchitecture of brain malformations. This article aims to review the use of DTI and FT in the evaluation of a variety of common, well-described brain malformations, in particular by pointing out the additional information that DTI and FT renders compared with conventional MR sequences. In addition, the relevant existing literature is summarized.
弥散张量成像(DTI)是一种先进的磁共振技术,可提供关于白质微观结构的定性和定量信息。在过去十年中,DTI 及其后处理工具纤维束追踪(FT)越来越多地用于研究脑畸形的微观神经结构。本文旨在回顾 DTI 和 FT 在评估各种常见、描述明确的脑畸形中的应用,特别是通过指出 DTI 和 FT 与常规磁共振序列相比提供的额外信息。此外,还总结了相关的现有文献。
