摘　　要：目的探讨超声以及MSCT诊断肝癌微血管侵犯(MVI)的一致性,并对2种影像学检查的诊断效能进行比较。方法收集82例肝癌患者的超声以及MSCT资料,以术后病理结果为金标准,对比分析超声以及MSCT诊断肝癌MVI的一致性及诊断效能。结果依据82例肝癌患者的术后病理结果,其中MVI阳性30例、阴性52例。术前MSCT与超声诊断肝癌MVI具有很强的一致性(Kappa系数=0.829,P<0.001)。术前超声预测肝癌MVI的敏感度、特异度以及准确度分别为76.67%(23/30)、67.31%(35/52)以及70.73%(58/82);术前MSCT预测肝癌MVI的敏感度、特异度以及准确度分别为83.33%(25/30)、73.08%(38/52)以及75.61%(63/82)。结论术前超声以及MSCT诊断肝癌MVI时具有较好的一致性,且2种检查方式具有较高的诊断效能。Objective To investigate the consistency of ultrasound and MSCT in diagnosing microvascular invasion(MVI)in hepatocellular carcinoma,and to compare the diagnostic efficiency of both two methods.Methods The ultrasound and MSCT data of 82 patients with hepatocellular carcinoma were collected.According to the postoperative pathological results,the consistency and diagnostic efficiency of ultrasound and MSCT in diagnosing MVI in hepatocellular carcinoma were compared.Results According to the postoperativepathological findings of 82 patients,30 cases were positive of MVI,while 52 cases were negative.The preoperative MSCT and ultrasound examinations had a strong consistency(Cohen's Kappa=0.829,P<0.001).The sensitivity,specificity and accuracy of preoperativeultrasound in predicting the MVI in hepatocellular carcinoma were 76.67%(23/30),67.31%(35/52)and 70.73%(58/82),respectively.The sensitivity,specificity and accuracy of preoperative MSCT in predicting hepatocellular carcinoma MVI were 83.33%(25/30),73.08%(38/52)and 75.61%(63/82),respectively.Conclusion Preoperative ultrasound and MSCT have good consistency and high diagnostic efficiency in diagnosing MVI in hepatocellular carcinoma.
