目的 :着重探讨菲立磁增强扫描对局灶性肝病的检出价值。方法 :收集经螺旋CT增强扫描及菲立磁MRI增强扫描且临床、手术病理证实局灶性肝病 2 6例 5 7个病灶 ,采用分组盲法ROC曲线分析对比评价菲立磁增强MRI与螺旋CT增强扫描对局灶性肝病的检出价值。结果 :联合平扫MRI+增强MRI与其它三种方法之间比较 ,Az最大为 0 975 0 ,P <0 0 5 ,单独菲立磁增强MRI的Az=0 9315虽然大于平扫MRI的Az=0 92 2 6 ,但两者间差异无显著性 ,P >0 0 5 ,CT与其它三种方法之间比较 ,病灶检出Az =0 82 70最小 ,P <0 0 5。结论 :菲立磁增强MRI对肝局灶性病变的检出价值优于螺旋CT增强扫描。联合分析平扫 +菲立磁增强MRI的肝局灶性病灶的检出价值优于单独分析菲立磁增强法。
Objective: To investigate the detection value of Feridex enhanced MRI in detecting focal liver disease. Methods: Twenty-six cases and 57 cases of focal liver disease were confirmed by enhanced spiral CT and enhanced MRI with contrast-enhanced MR imaging. Enhancement of the detection of focal liver disease value. Results: Compared with the other three methods, the maximal Az was 0 975 0, P 0 05, while Az = 0 9315 of the single Philippine magnetic resonance contrast enhanced MRI was higher than that of the plain MRI scan Az = 0 92 2 6, but there was no significant difference between them (P> 0.05). The difference between CT and other three methods was the smallest (P <0.05). Conclusion: The detection of focal liver lesions by Philippine magnetic resonance imaging is better than that of helical CT. The combined detection of pleural enhancement + MRI enhancement of focal liver lesions was better than that of Philippine enhancement alone.
