【摘要】：目的探讨声速匹配(SSC)技术对肝脏良恶性实性肿物的鉴别诊断效能。方法选取手术切除的肝脏实性肿物90例份,其中良性肿物57例份(良性组)、恶性肿物33例份(恶性组),另选肿物周围正常肝组织58例份(对照组),测量各组区域速度指数(ZSI);构建良恶性肿物ZSI的受试者工作特征曲线,确定诊断肿物良恶性的最佳ZSI临界值。结果良性组、恶性组、对照组ZSI分别为(18.91±10.10)、(37.15±8.62)、(15.78±8.80)m/s,恶性组分别与良性组、对照组比较,P均0.05。约登指数最大值对应的ZSI为临界值(25 m/s),此值诊断实性肿物良恶性的敏感度为97%,特异度为78.9%。结论 SSC技术鉴别诊断肝脏实性肿物良恶性有价值,为超声评估肝脏肿物性质提供新的量化诊断参考指标。
[Abstract]:Objective to study the differential diagnosis of benign and malignant solid tumors of liver by using SSCS technique. Methods 90 cases of hepatic solid tumor were selected. 57 cases of benign tumor (benign group, 33 cases of malignant tumor) (malignant group, 58 cases of normal liver tissue around the tumor) were selected (control group, regional velocity index of each group was measured, and the operating characteristic curve of benign and malignant tumor ZSI was constructed. To determine the best ZSI critical value for the diagnosis of benign and malignant tumors. Results the ZSI of benign group, malignant group and control group were 18.91 卤10.10 ~ (-1) ~ 37.15 卤8.62 ~ (-1) 渭 m / s, respectively. The ZSI of malignant group and benign group were 15.78 卤8.80 m / s, respectively, compared with those of benign group and control group (P < 0.05). The ZSI corresponding to the maximum value of the Jorden index is a critical value of 25 m / s ~ (-1). The sensitivity and specificity of this value for the diagnosis of benign and malignant solid tumors are 97 and 78.9 respectively. Conclusion SSC technique is valuable in differentiating benign and malignant liver masses, and provides a new quantitative diagnostic index for the evaluation of liver masses by ultrasound.
