摘要
目的探讨分析超声造影定性诊断肝脏局灶病变中的特异性,灵敏度及符合率。方法选取2018年1月至2020年10月收治肝脏局灶性病变患者150例,所有患者均经过手术病理确诊,患者均接受常规超声、以及超声造影检查诊断,对两种不同诊断方式的结果进行对比分析。结果超声造影诊断病理分型总符合率为92.00%,相较于病理分型总符合率73.33%的常规超声诊断明显较高(P<0.05);超声造成诊断良恶性病变符合率94.12%、89.23%,对比于常规超声诊断的良恶性病变符合率71.76%、75.38%要较高(P<0.05);超声造影诊断的准确性、特异性、敏感性以及阳性、阴性预测值,相较于常规超声诊断结果要明显较优(P<0.05)。结论临床在肝脏局灶性病变诊断中,超声造影诊断无论是对病理分型、亦或是良恶性病变的诊断符合率均较高,且诊断准确性、特异性等也要明显高于常规超声诊断结果,具有较高的临床推广性。
Objective To investigate the specificity,sensitivity and coincidence rate of contrast-enhanced ultrasound(CEUS)in the qualitative diagnosis of liver focal lesions.Methods A total of 150 patients with liver focal lesions who were treated in our hospital from January 2018 to October 2020 enrolled in the study.All the patients were confirmed by surgery and pathology,who underwent conventional ultrasound examination and contrast-enhanced ultrasound(CEUS)diagnosis.The results of the two different diagnostic methods were observed and compared.Results The total coincidence rate of CEUS diagnosis was 92%,which was significantly higher than that(73.33%)by conventional ultrasonography(P<0.05).The coincidence rates of benign and malignant lesions diagnosed by CEUS were 94.12%and 89.23%,which were significantly higher than those(71.76%and 75.38%)by conventional ultrasound(P<0.05).The accuracy,specificity,sensitivity and positive and negative predictive values of CEUS diagnosis were significantly better than those by conventional ultrasound diagnosis(P<0.05).Conclusion The diagnostic accuracy and specificity of CEUS are superior to those by conventional ultrasonography in the diagnosis of liver focal lesions,and in the aspects of pathological types,and coincidence rates of benign and malignant lesions,therefore,which is worthy of clinical promotion.
