摘要：Perisylvian language areas are connected through the arcuate fasciculus, a long association pathway that can be visualised using MR-based diffusion tensor imaging (DTI) tractography (Catani et al., 2005). Volumetric measurements of the arcuate fasciculus in healthy subjects show that direct connections between temporal and frontal areas are left-lateralised in most but not all subjects (Catani et al., 2007). In this study, we combined language assessments (Western Aphasia Battery-Revised (WAB-R); Kertesz, 2007) and DTI tractography in patients with post-stroke aphasia to identify anatomical predictors of recovery based on latéralisation patterns (Figure 1 .A).
