摘　　要：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。Objective To observe the value of SWI in detection of siderotie 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 ＊ WI, 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.
