超声实时应变成像技术在乳腺疾病性质鉴别诊断中的价值

目的探讨超声实时应变成像技术（量化超声弹性成像技术）诊断乳腺病变良、恶性的最佳诊断界点及其诊断价值。方法 分析经手术病理证实的83例不同病理类型良恶性乳腺结节的弹性成像检查结果,根据恶性肿瘤的特点,对病灶整体硬度比（病灶整体与正常腺体组织比值）与局部硬度比（病灶局部（1cm2）最高值-病灶局部最低值）进行量化分析;通过受试者工作特征（ROC）曲线了解该技术对乳腺疾病性质鉴别诊断的价值。结果病灶整体硬度比值对乳腺病灶良、恶性诊断ROC曲线下面积为0.926,其敏感性、特异性、阳性预测值、阴性预测值及准确性分别为：81.30%、92.20%、93.75%、92.15%和92.55%。病灶局部硬度比值对乳腺病灶良、恶性诊断的ROC曲线下面积为0.939,其敏感性、特异性、阳性预测值、阴性预测值及准确性分别为：90.60%、96.10%、96.87%、94.08%和95.18%。结论超声实时应变成像技术使用更为简便、客观、准确,有助于乳腺肿块的良、恶性鉴别。

The Diagnostic Value of Quantitive Ultrasound Elastography to Benign and Malignant Breast Lesions

Objective To explore the best cutoff point of the quantitive ultrasound elastography for differentiating malignant and benign breast lesions and to assess its diagnostic value.Methods A retrospective analysis was used to analyze the results of UE for 83 benign and malignant breast lesions and their pathological types have been confirmed by surgery.According to the features of malignant breast lesions,the ratio of the whole hardness and partly hardness of the lesions were used for quantitive evaluating.The d...
