 【摘要】 目的 评估原发性肝癌介入术后完全缓解病灶磁共振表观扩散系数(ADC)值测量的可重复性和一致性,为临床应用提供参考。方法 对21个完全缓解病灶在术后第1、3、6个月时由同一名医师同一序列测量ADC值、不同医师间隔1周测量病灶的ADC 值,通过计算组内相关系数(ICC)值及绘制BlandAltman图表确定ADC值测量的可重复性及一致性。ICC值大于0.75表示信度良好,可重复性高,75%的位点位于BlandAltman图95%的置信区间的参考线内,其一致性高。结果 A医师术后1、3、6个月测量ICC值分别为0.928、0.878、0.934;B医师术后1、3、6个月测量ICC值分别为0.873、0.940、0.871,1周前不同时间A、B医师1、3、6个月测量ICC值分别为0.854、0.940、0.960;1周后不同时间A、B医师术后1、3、6个月测量ICC值分别为:0.788、0.945、0.858,均大于0.75,提示可信度较高,可重复性强。90%的位点BlandAltman图95%的置信区间的参考线内,数值测量的可重复性高。结论 HCC完全缓解病灶的ADC值稳定,测量具有较高的一致性和可重复性,可以动态观察原发性肝癌介入治疗后病灶的稳定程度,可及时有效的评估巩固治疗时机。
