Susceptibility-weighted imaging (SWI) is a method that uses the intrinsic nature of local magnetic fields to enhance image contrast in order to improve the visibility of various susceptibility sources and to facilitate diagnostic interpretation. In this article, we review the basics of SWI, with discussions on data acquisition, reconstruction and post-processing. In addition, we show a few clinical applications of SWI, such as the imaging of stroke, traumatic brain injury, the carotid vessel wall and siderotic nodules in cirrhotic liver.
