The corpus callosum is the major axonal commissure of the brain, connecting the two cerebral hemispheres and providing communication between the cortical and subcortical neurons. With MR imaging in the sagittal plane, the corpus callosum can be depicted in great detail. We review the normal anatomy, development, and process of myelination of the corpus callosum. The MR features of various pathologic conditions involving the corpus callosum are described. Finally, we discuss the evolving role of MR imaging in neuropsychiatric diseases with respect to the corpus callosum.
胼胝体是大脑主要的轴突连合纤维，连接两侧大脑半球，并为皮质和皮质下神经元提供通信。通过矢状面磁共振成像，可以非常详细地描绘胼胝体。我们回顾了胼胝体的正常解剖结构、发育过程和髓鞘形成过程。描述了涉及胼胝体的各种病理状况的磁共振特征。最后，我们讨论了磁共振成像在涉及胼胝体的神经精神疾病中不断演变的作用。
