消化道肿瘤肝转移61例超声造影分析

目的用定量的方法探讨消化道肿瘤肝转移的超声造影特点。方法对61例消化道肿瘤肝转移病人进行超声造影检查，并对超声检查过程进行定量分析，同时与原发性肝癌病人的相应参数进行比较。结果4组消化道肿瘤病人共5个定量参数指标差异无统计学意义（P〉0．05）。原发性肝癌组的峰值增强强度高于肝转移组（P〈0.01），原发性肝癌组的50％清除斜率低于肝转移组（P〈0．01）。结论消化道来源的肝脏转移病灶在超声造影上有相近的表现，可以利用超声造影检查对消化道肿瘤的肝脏转移病灶进行定量诊断，并与原发性肝癌进行鉴别诊断，有一定的临床应用价值。

Contrast-enhanced Ultrasound Quantilative Analysis of hepatic metastasis of alimentary tract cancer: A report of 61 cases

Objective To Quantilatively Analyze the feature of hepatic metastasis of alimentary tract cancer in Contrast-enhanced Ultrasound(CEUS).Methods Sixty-one patients with hepatic metastasis of alimentary tract cancer were observed with Contrast-enhanced Ultrasound.The acoustic quantified parameter were analyzed.And the results were compared with the counterparts of primary hepatic carcinoma patients.Results Four groups had no significant differences in the five parameters of quantitative analysis of Contrast-enhanced Ultrasound(P>0.05).The peak enhancement intensity in liver metastases were significantly lower than those in PHCs(P<0.01)The wash-out 50% slope in liver metastases were significantly faster than those in PHCs(P<0.01).Conclusion Hepatic metastasis of alimentary tract cancer in Contrast-enhanced Ultrasound have the same feature.The parameter of CEUS are be used to differentially diagnose hepatic metastasis of alimentary tract cancer and primary hepatic carcinoma,which have clinical value.
