【摘要】：目的探讨超声造影(CEUS)与声辐射力脉冲成像技术(ARFI)在肝脏良恶性肿瘤鉴别诊断中的临床应用价值。方法对202例253个病灶经病理确诊的肝肿瘤(原发性肝癌60例,转移性肝癌40例,肝内胆管细胞癌18例,肝血管瘤50例,局灶性结节性增生16例,肝硬化增生结节18例)分别进行CEUS及ARFI检查。采用双盲法分析两种超声技术对肝脏良恶性肿瘤的诊断价值。结果 CEUS诊断肝脏肿瘤良恶性的灵敏度、特异度、准确度分别为88.96%、88.89%、88.93%。ARFI诊断肝脏肿瘤良恶性的灵敏度、特异度、准确度分别为79.31%、75.93%、77.89%。CEUS联合ARFI诊断肝脏肿瘤良恶性的灵敏度、特异度、准确度分别为91.72%、92.59%、92.09%。结论 CEUS对肝肿瘤良恶性的鉴别诊断优于ARFI;但两种技术联合应用可提高肝脏良恶性病灶的鉴别诊断,降低漏诊率和误诊率。
[Abstract]:Objective to evaluate the clinical value of contrast-enhanced (CEUS) and acoustic power pulse imaging (ARFI) in differential diagnosis of liver benign and malignant tumors. Methods A total of 202 cases (60 cases of primary liver cancer, 40 cases of metastatic liver cancer, 18 cases of intrahepatic cholangiocarcinoma, 50 cases of hepatic hemangioma and 16 cases of focal nodular hyperplasia) were studied. CEUS and ARFI were performed in 18 patients with hepatic cirrhosis and hyperplastic nodules. Double blind method was used to analyze the diagnostic value of two ultrasound techniques for liver benign and malignant tumors. Results the sensitivity, specificity and accuracy of CEUS in the diagnosis of benign and malignant liver tumors were 88.96 and 88.89, respectively. The sensitivity, specificity and accuracy of CEUS in the diagnosis of benign and malignant liver tumors were 79.31 and 75.93, respectively. The sensitivity, specificity and accuracy of 77.89%.CEUS combined with ARFI in the diagnosis of benign and malignant liver tumors were 91.722 and 92.59, respectively. Conclusion the differential diagnosis of benign and malignant liver tumors by CEUS is superior to that of ARFI;, but the combination of two techniques can improve the differential diagnosis of benign and malignant liver lesions, and reduce the rate of missed diagnosis and misdiagnosis.
