摘要： 弓形束是人类语言网络的重要组成部分。扩散张量纤维束示踪成像（DTT）是目前在体无创性显像大脑白质纤维束的最常用方法。本文对DTT 在显像弓形束解剖结构和功能特性基础研究，以及神经外科手术临床研究中的进展进行简要概述，但其准确性尚待进一步研究。

Abstract: Arcuate fasciculus (AF) is a crucial part of human language network. Diffusion tensor tractography (DTT) is the most common method for reconstruction of white matter fibers in vivo. DTT is widely applied in both basic researches on the anatomical structure and functions of AF and clinical studies on AF navigation. However, the validity of AF with DTT needs further investigation in the future.
