The Susceptibility-weighted (SWI) imaging is a recent MRI sequence that shows the magnetic susceptibility differences of various tissues. A large number of neurological / neurosurgical diseases can benefit with this MRI sequence. The basic physics principles are reviewed and also its clinical application in several brain pathologies in adults and in paediatrics, mainly vascular, tumors and neurodegenerative/genetic disorders. Some clinical cases show the utility of SWI. The anatomic detail of some brain structures, the deep venous system and mesencephalic structures is shown.
磁敏感加权成像（SWI）是一种新型的磁共振成像序列，可显示不同组织间的磁敏感性差异。大量神经科/神经外科疾病均可通过该磁共振成像序列受益。本文回顾了其基本物理原理，以及它在成人及儿童多种脑部病变（主要是血管性、肿瘤性及神经退行性/遗传性疾病）中的临床应用。一些临床病例展示了SWI的实用性。文中还展示了一些脑结构、深部静脉系统及中脑结构的解剖细节。
