Susceptibility-weighted imaging (SWI) is a relatively new MRI sequence relying on susceptibility differences between adjacent tissues to produce an image. It is extremely sensitive for detection of blood products (hemosiderin, ferritin), deoxygenated blood, calcium, iron, and small vein depiction. Little information is available in the literature to describe common findings seen using this imaging sequence. The potential of this new sequence can be reviewed in comprehensive article "Susceptibility-Weighted Imaging of the Brain: Current Utility and Potential Applications" available online. SWI is an extremely useful adjunct to current MRI sequences of the brain and is advocated for inclusion into routine Neuroimaging protocols.
磁敏感加权成像（SWI）是一种相对较新的 MRI 序列，它依赖于相邻组织之间的磁化率差异来产生图像。它对血液产物（含铁血黄素、铁蛋白）、去氧血红蛋白、钙、铁和小静脉的显示非常敏感。目前文献中关于这种成像序列的常见表现的信息很少。可以在网上查阅到一篇全面的文章“脑磁敏感加权成像：当前的应用价值和潜在应用”来了解该新序列的潜在应用。SWI 是脑内目前 MRI 序列的一个非常有用的补充，并且提倡将其纳入常规神经影像学检查方案中。
