To observe the value of SWI in detection of siderotic nodule (SN) in patients with liver cirrhosis. Methods Forty-six liver cirrhosis patients with SN underwent T1WI, T2WI, T2" WI and SWI. Subsequently, the images of each technique were analyzed. Results Compared to T1WI, T2WI and T2 Wl, SWI detected more SN of cirrhosis with higher definition. Conclusion SWI can display SN of cirrhosis clearly and sensitively, therefore providing important information for clinical evaluation of SN.%目的 探讨磁敏感加权成像(SWI)探测肝硬化铁质沉积再生结节(sN)的价值.方法 对46例肝硬化患者行常规MR T1W、T2W、T2*W及SWI检查.对各方法采集的图像进行分析,评估各方法探查SN的能力.结果 SWI较常规T2W、T1W、T2*W技术在探测结节数目和结节的可见度方面有明显优势.结论 SWI技术能够更清晰、全面地显示肝硬化结节,检出肝硬化结节更敏感,可为临床更准确地评估肝硬化患者的病情提供重要影像学信息.
