本研究结合结构磁共振成像（sMRI）和扩散张量MRI（DT-MRI），研究了18名钢琴家和21名年龄匹配的非音乐家的灰质密度（GMD）和白色完整性（WMD）。这些钢琴家平均在12岁时开始钢琴训练。基于体素的sMRI数据的形态测量显示，钢琴家在左侧初级感觉运动皮层和右侧小脑中具有较高的GMD。DT-MRI数据的基于体素的分析表明，钢琴家在内囊的右后肢具有较高的各向异性分数（FA）（指示较高的SNR）。sMRI和DT-MRI结果表明，与非音乐家相比，钢琴家的GMD和GMD可能在青春期甚至成年早期表现出与运动相关的增加。(C)2008爱思唯尔爱尔兰有限公司保留所有权利。
The current study combined structural magnetic resonance imaging (sMRI) and diffusion tensor MRI (DT-MRI) to investigate both gray matter density (GMD) and white matter integrity (WMI) in 18 pianists and 21 age-matched non-musicians. The pianists began their piano training at a mean age of 12. Voxel-based morphometry of the sMRI data showed that the pianists had higher GMD in the left primary sensorimotor cortex and right cerebellum. Voxel-based analysis of the DT-MRI data showed that pianists had higher fractional anisotropy (FA) (indicating higher WMI) in the right posterior limb of the internal capsule. The sMRI and DT-MRI results indicate that both the GMD and WMI of pianists may exhibit movement-related increases during adolescence or even early adulthood compared with non-musicians.
