目的探讨非探头加压式弹性应变率比值法对乳腺癌的诊断价值.资料与方法对54例乳腺疾病患者共66个病灶行非探头加压式超声弹性成像检查,计算正常腺体组织与病变区组织的弹性应变率比值(SR),以病理结果为诊断标准,绘制 ROC 曲线以及鉴别良恶性病灶的最佳诊断界点.结果病理诊断恶性病灶43个,良性病灶23个;恶性病灶 SR 为3.515±1.227,良性病灶SR 为1.697±0.618,两者差异有统计学意义(P<0.05).ROC 曲线下面积为0.903,当最佳诊断界点为2.51时,诊断的敏感性为88.4%,特异性为91.3%.结论非探头加压式超声弹性成像对乳腺癌的诊断具有重要的临床价值.

Purpose To assess the value of ultrasonic elastography strain ratio method (without pressure) in diagnosing breast cancer. Materials and Methods Fifty-four patients with sixty-six masses were examined by UE strain ratio method (without pressure) to calculate the stain ratio (SR) of normal glandular tissue and lesions, and confirmed by pathology. ROC curve was used to determine the cut-off point of SR. Results There were 43 malignant lesions and 23 benign lesions. The mean SR of malignant lesions was 3.515±1.227, while the mean SR of benign lesions was 1.697±0.618 (P<0.05). The area under the curve was 0.903. While taking 2.51 as the cut-off point of SR, the sensitivity was 88.4%, and the specificity was 91.3%. Conclusion Ultrasonic elastography strain ratio method (without pressure) is of significant value in clinical application.
