磁敏感加权成像(SWI)是一种全新的、反映组织间磁敏感差异对比的成像技术,具有三维、高分辨率、高信噪比的特点。脑肿瘤内常有微血管形成及微量出血,并可有钙化,对这些细节的识别对肿瘤的定性有重要的作用,并可用于指导选择最佳治疗方案,而SWI对于静脉结构、出血代谢物、矿物质
Magnetic susceptibility weighted imaging (SWI) is a new imaging technique that reflects the contrast between the magnetic susceptibility of tissues. It has the characteristics of three-dimensional, high resolution and high signal-to-noise ratio. Microvessel formation and micro-hemorrhage often occur in brain tumors, and may have calcification. Identification of these details plays an important role in the qualitative diagnosis of the tumor and can be used to guide the selection of the best treatment plan. However, SWI is not sensitive to venous structure, hemorrhagic metabolites, Minerals
