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(P<0.05)。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。
Objective To analyze the sensitivity, specificity and accuracy of ultrasound elastography and color Doppler ultrasound in the diagnosis of benign and malignant breast lesions. Methods Statistical analysis of 390 patients with clinical data. Results 468 breast lesions, pathological results of 254 cases of benign (292); 136 cases of malignant (176). The sensitivity of ultrasound elastography in the diagnosis of malignant space-occupying lesions was 87.5% (154/176), the specificity was 95.2% (278/292) and the accuracy was 92.3% (432/468). The color Doppler ultrasonography The sensitivity of flow classification to the diagnosis of malignant space-occupying lesions was 69.3% (122/176), the specificity was 71.9% (210/292) and the accuracy was 75.2% (176/468) The diagnostic sensitivity was 76.5% (104/136), the specificity was 62.2% (102/164) and the accuracy was 68.7% (206/300). Color Doppler ultrasonographic grading combined with RI in malignant mass The diagnostic sensitivity of lesions was 55.7% (98/176), specificity was 84.9% (248/292) and the accuracy was 73.9% (346/468). The sensitivity of ultrasound elastography in the diagnosis of benign and malignant breast lesions Sex, specificity and accuracy were significantly higher than color Doppler ultrasound (P <0.05). Conclusion The sensitivity, specificity and accuracy of ultrasound elastography in the diagnosis of benign and malignant breast lesions are higher than those of color Doppler ultrasound.
