【摘要】：目的分析超声弹性成像与彩色多普勒超声在乳腺良恶性占位病变诊断中的敏感性、特异性及准确性。方法统计分析390例患者的临床资料。结果乳腺占位性病灶468个,病理结果 254例良性(292个);136例恶性(176个)。超声弹性成像对恶性占位性病灶诊断的敏感性为87.5%(154/176),特异性为95.2%(278/292),准确性为92.3%(432/468);彩色多普勒超声血流分级对恶性占位性病灶诊断的敏感性为69.3%(122/176),特异性为71.9%(210/292),准确性为75.2%(176/468);RI对恶性占位性病灶诊断的敏感性为76.5%(104/136),特异性为62.2%(102/164),准确性为68.7%(206/300);彩色多普勒超声血流分级联合RI对恶性占位性病灶诊断的敏感性为55.7%(98/176),特异性为84.9%(248/292),准确性为73.9%(346/468);超声弹性成像在乳腺良恶性占位病变诊断中的敏感性、特异性及准确性均显著高于彩色多普勒超声(P0.05)。结论超声弹性成像在乳腺良恶性占位病变诊断中的敏感性、特异性及准确性均较彩色多普勒超声高。
[Abstract]:Objective to analyze the sensitivity, specificity and accuracy of elastography and color Doppler ultrasonography in the diagnosis of benign and malignant breast lesions. Methods the clinical data of 390 patients were analyzed statistically. Results there were 468 lesions in the mammary gland, and there were 254 cases of benign lesions (292 lesions) and 136 cases of malignant lesions (176 cases). The sensitivity, specificity and accuracy of ultrasound elastography were 87.5% (154 / 176), 95.2% (278 / 292) and 92.3% (432 / 468), respectively, while the sensitivity, specificity and accuracy of color Doppler flow classification were 69.3% (122 / 176), 71.9% (210 / 292) and 75.2% (176p 468), respectively. The sensitivity, specificity and accuracy of malignant space-occupying lesions were 76.5% (104 / 136), 62.2% (102 / 164) and 68.7% (206 / 300), respectively, while the sensitivity of color Doppler ultrasonography combined with RI was 55.7% (98 / 176), specificity was 84.9% (248r292), accuracy was 73.9% (34.6 / 468). Like in the diagnosis of benign and malignant breast lesions, Specificity and accuracy were significantly higher than color Doppler ultrasound (P0.05). Conclusion Ultrasound elastography is more sensitive, specific and accurate than color Doppler ultrasound in the diagnosis of benign and malignant breast lesions.
