【摘要】 目的探讨超声弹性成像在GI-RADS 4类盆腔包块良恶性鉴别诊断中的应用价值。方法对彩色多普勒超声检查发现的盆腔包块病灶(185例)进行妇科影像报告和数据系统(GI-RADS)分类,并将划归GI-RADS 4类的22个包块行经阴道超声弹性成像检查,将弹性评分与最终病理结果进行对比分析。结果良性病变14例(弹性评分1-2分),恶性病变8例(弹性评分3-5分),良、恶性病变超声弹性成像评分结果差异有统计学意义(P<0.05)。超声弹性成像对彩超诊断未定性的盆腔包块良恶性鉴别诊断的敏感性、特异性、阳性预测值及阴性预测值分别为87.5%、85.7%、77.8%、92.3%,准确性可达86.4%。结论超声弹性成像对彩色多普勒超声未能准确定性诊断的盆腔包块良恶性鉴别诊断准确率高,具有广阔的临床应用前景。更多还原

【Abstract】 Objectives To investigate the value of ultrasonographic elastography in the differential diagnosis of benign and malignant pelvic masses of Gynecologic Imaging Reporting and Data System 4(GI-RADS 4).Methods Color Doppler ultrasonography was performed on 185 pelvic masses,and the findings were classified by the Gynecologic Imaging Reporting and Data System(GI-RADS).Transvaginal ultrasonographic elastography was used on 22 lesions which were classified to GI-RADS 4(probably malignant).The elasticity color code(pattern 1-5)were compared with final pathological results.Results 14 benign lesions(elasticity color pattern 1-2)and 8malignant lesions(elasticity color pattern 3-5)were finally diagnosed.There were statistically difference between benign lesions and malignant lesions in elastic scores(P<0.05).The sensitivity,specificity,positive predictive value and negative predictive value of ultrasound elasticity imaging were 87.5%,85.7%,77.8% and 92.3%,respectively,and the accuracy was 86.4%.Conclusion Transvaginal ultrasonographic elastography has widely application prospect in the differential diagnosis of benign and malignant pelvic masses which were classified into GI-RADS 4.更多还原
