1、探讨彩色多普勒和超声造影在肝癌诊断中的应用[摘要]目的探討彩色多普勒和超声造影在肝癌诊断中的应用价值。方法方便选取2015年1月—2017年12月在该院住院治疗75例肝癌患者为观察组,所有患者均经手术病理或穿刺病理确诊,另选取102例非肝癌患者为对照组。所有患者均接受彩色多普勒超声、超声造影检查,综合两种检查方法的特征建立logistics回归模型,运用逐步引入-剔除法对各个影响因素进行多因素logistics回归分析,以评估彩色多普勒和超声造影在肝癌诊断中的应用效果。结果经单因素分析,肝癌患者病灶后方及内部回声、病灶大小、边缘、能量多普勒、晕
2、环征、病灶彩色多普勒信号分级以及脉冲多普勒频谱均为主要危险因素。经多因素logistics回归分析,晕环征(OR=7.897,95%可信区间=2.087~30.251)、能量多普勒(OR=13.252,95%可信区间=1.789~91.487)、造影剂增强模式(OR=10.154,95%可信区间=1.856~55.585)是预测肝癌的独立危险因素。结论在肝癌的临床诊断上,晕环征、能量多普勒、造影剂增强模式具有准确的预测价值,以超声特征诊断肝脏占位性病变的logistics回归分析可与肝内其他占位性病变的鉴别,有利于提高临床诊断的准确率,为疾病治
