Susceptibility-Weighted Imaging (SWI) is a relatively new magnetic resonance imaging (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. This article is an comprehensive review of appearances across the spectrum of brain pathology encountered in routine clinical practice.
A retrospective review of 400 MRI Brain examinations was performed by one fellowship trained Neuroradiologist with 5 years experience (SB) and one general radiologist (RR). Agreement was by consensus observing normal and pathological imaging features seen in SWI sequences.
Results are presented as a comprehensive pictorial review highlighting the key imaging findings observed and new directions using SWI.
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）是一种相对较新的磁共振成像（MRI）序列，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、铁和小静脉的显示具有极高的敏感性。目前文献中关于使用这种成像序列的常见表现的信息很少。本文全面回顾了在常规临床实践中遇到的各种脑病理学表现。
由一位具有 5 年经验的神经放射学研究员（SB）和一位普通放射科医师（RR）对 400 例 MRI 脑检查进行了回顾性分析。通过观察 SWI 序列中的正常和病理影像学特征来达成共识。
结果以全面的图像回顾形式呈现，突出了观察到的关键影像学表现和 SWI 的新应用方向。
SWI 是脑磁共振成像序列的极好补充，并倡导将其纳入常规神经影像学方案中。
