摘　　要：MR T2 mapping可以通过测量组织T2值反映组织内水含量的变化,最早被应用于关节软骨和心肌病变的评估中。与传统的磁共振结构成像相比,它具有客观、精准、重复性高等优点。近年来,它在外周神经疾病中的应用越来越广泛。本文就T2 mapping的基本成像原理、在正常周围神经以及在不同种类周围神经疾病中的应用进展予以综述。MR T2 mapping can reflect the content of water within tissues by measuring T2 relaxation times,which was used in the evaluation of articular cartilage and myocardium at first.Compared with conventional MR imaging,it is more objective and precise.In recent years,T2 mapping has been increasingly applied in peripheral nerve disorders.The basic principles of T2 mapping and the research progress of its applications in normal peripheral nerves and various kinds of peripheral nerve disorders are reviewed in this paper.
