超声造影参数成像对不典型表现的肝脏局灶性病变的诊断价值

摘要

目的 探讨超声造影(CEUS)动态血管模型参数成像(DVP)在不典型CEUS表现的肝脏局灶性病变(FLLs)诊断中的价值.方法 对262个FLLs行CEUS检查,据造影剂廓褪情况将FLLs分为典型表现组及不典型表现组.两组的CEUS录像资料分别运用Sonoliver 1.0软件进行分析.所有病例均经临床和病理证实.结果 主观判断与量化分析的结果 之间的一致性相比较,典型表现组较好(Kappa值=0.904),不典型表现组一般(Kappa值=0.403)；主观判断与量化分析的定性诊断准确性相比较,典型表现组的2个准确性之间的差异没有统计学意义(P＞0.05),不典型表现组量化分析的诊断准确性要高于主观判断(P＜0.05).结论 结合运用CEUS参数成像软件进行分析,可以明显提高不典型病灶的定性诊断准确性.%Objective To investigate the diagnostic value of quantitative analysis and parametric imaging using dynamic vascular patterns in atypical focal liver lesions. Methods 262 focal liver lesions(FLLs) were divided into typical and atypical group by CEUS expurgation. The data of two groups was analyzed by Sonoliver 1. 0 software. All FLLs were confirmed by clinic or pathology. Results The agreement of subjective judgment and quantitative analysis were compared, the agreement of typical group (Kappa = 0. 904) was better than that of atypical group (Kappa = 0. 403). The diagnostic accuracy of subjective judgment and quantitative analysis were compared, there were no statistical differences between diagnostic accuracy in typical group(P>0. 05), the diagnostic accuracy of quantitative analysis was higher than that of subjective judgment in atypical group(P<0. 05). Conclusions Parametric imaging of CEUS can significantly increase the diagnostic accuracy in atypical lesions.
