目的 探讨超声联合彩色多普勒超声 (彩超 )检查对卵巢良、恶性肿瘤的诊断价值。方法 对 15 2例疑卵巢肿瘤的病人行常规超声和彩超检查 ,观察其形态结构、血流信号分布及血流阻力、血流速度的特征 ;对肿块的良、恶性进行术前诊断 ;并计算常规超声检查和超声联合彩超检查的诊断敏感性、特异性、阳性预测值、阴性预测值。结果 99例良性、49例恶性卵巢肿瘤经病理证实常规超声检查诊断的敏感性为 80 % ,特异性为 81% ,阳性预测值为 6 7% ,准确性为 80 % ;超声联合彩超检查诊断的敏感性为 86 % ,特异性 97% ,准确性 99% ,阳性预测值为 93.8% .结论 超声联合彩超检查能提高超声诊断卵巢肿瘤的特异性和阳性预测值 ,更具有临床实用价值。
Objective To investigate the diagnostic value of ultrasonography combined with color Doppler ultrasonography (Doppler ultrasound) in benign and malignant ovarian tumors. Methods Fifty-two patients with suspected ovarian tumors underwent routine ultrasound and color Doppler ultrasound examinations. The morphological structure, distribution of blood flow signals and the characteristics of blood flow resistance and blood flow velocity were observed. The benign and malignant tumors were preoperatively diagnosed. The diagnostic sensitivity, specificity, positive predictive value and negative predictive value of routine ultrasound and ultrasound combined with color Doppler ultrasound examination. Results 99 cases of benign and 49 cases of malignant ovarian neoplasms confirmed by pathology routine diagnostic ultrasound was 80%, specificity was 81%, the positive predictive value was 67%, the accuracy of 80%; ultrasound combined with color Doppler ultrasound diagnosis The sensitivity was 86%, the specificity was 97%, the accuracy was 99% and the positive predictive value was 93.8% .Conclusion Ultrasound combined with color Doppler ultrasonography can improve the specificity and positive predictive value of ultrasound in the diagnosis of ovarian tumors, and has more clinical practical value.
