超声造影与MRI诊断乳头溢液性病变的对比研究

Comparative study of contrast-enhanced ultrasound and MRI used in breast intraductal lesions

目的探讨超声造影和MRI检查在乳头溢液性病变诊断中的影像学特征。方法对26例乳头溢液患者行超声造影和MRI检查,分析两种检查方法的图像特征,比较两种检查方法对病灶良恶性的诊断符合率。结果超声造影和MRI对病灶诊断的敏感性、特异性、阳性预测值、阴性预测值及准确性分别为81.81%、86.67%、81.81%、86.67%、84.62%以及63.64%、80.00%、70.00%、75.00%、73.08%。结论超声造影和MRI对乳头溢液性病变性质的诊断均有重要价值。

Objective To investigate the image features of contrast-enhanced ultrasound（CEUS） and MRI in diagnosing breast intraduetal lesions. Methods Twenty-six patients with intraductal lesions of breast were examined with CEUS and MRI. The image features of the two methods were analyzed. The coincidence rate of the two methods in diagnosing benign and malignant lesions was compared. Results The sensitivity, specificity, positive predictive value, negative predictive value and accuracy rate of CEUS and MRI in 26 patients were 81.81%, 86.67%, 81.81%, 86.67%, 84.62% and 63.64%, 80%, 70%, 75%, 73.08%. Conclusion CEUS and MRI are important in diagnosing breast intraductal lesions.
