Susceptibility-weighted imaging (SWI) has become a key MR sequence in pediatric neuroimaging. The usage of SWI has significantly expanded recently. The strength of SWI lies not just in its ability to identify hemorrhage, calcium or nonheme iron by virtue of its susceptibility artifact, but also more importantly, the blood oxygen level dependent venography principle whereby several diseases can be diagnosed earlier. We are continuing to harness the power of SWI in the field of pediatric neuroimaging. In this paper, we will make a comprehensive review and discuss the utility of SWI in pediatric neuroimaging in establishing the diagnosis, differential diagnosis, and also understanding the pathomechanism of various pediatric brain pathologies.
磁敏感加权成像（SWI）已成为儿科神经影像学中的关键磁共振序列。SWI的应用近来有了显著扩展。SWI的优势不仅在于凭借其磁敏感伪影识别出血、钙或非血红素铁的能力，更重要的是，其基于血氧水平依赖静脉成像原理，能够更早地诊断多种疾病。我们在儿科神经影像学领域持续发挥SWI的作用。在本文中，我们将进行全面综述，并讨论SWI在儿科神经影像学中对于确立诊断、鉴别诊断以及理解各种儿科脑部病变病理机制的效用。
