目的 探讨超声弹性成像技术对乳腺良恶性肿瘤的鉴别诊断价值。方法 对我院186例患者的205个乳腺肿块,行超声弹性成像检查,评分采用改良5分法,4~5分为恶性,1~3分为良性,并以病理诊断作为金标准。结果 灵敏度80%,特异度98.7%,准确率94.1%,阳性预测值95.2%,阴性预测值93.9%,一致性检验χ2为138.9,P<0.01。被误诊为良性的肿块分别是浸润性癌4例,黏液腺癌1例,髓样癌3例,纤维腺癌2例;被误诊为恶性的均为纤维腺瘤。结论 超声弹性成像检查在鉴别诊断乳腺肿瘤良恶性方面准确率较高。
Abstract
Objective To study the value of ultrasonic elastography in diagnosis of benign and malignant breast tumors. Methods Ultrasound elastography was conducted in 186 patients with 205 breast mass in this hospital by using the improved method of scoring 5 points: 4-5 was malignant, 1-3 was begign. Results The data showed that diagnostic sensitivity was 80%, specificity 98.7%, accuracy 94.1%, PPV 95.2%, NPV 93.9%, χ2138.9,P<0.01. It also proved that the begign breast lumps of misdiagnosis were: 4 invasive carcinoma, 1 mucinous adenocarcinoma, 3 carcinoma spongiosum, 2 fibroadenoma and the misdiagnosed malignant ones were fibroadenoma. Conclusions Ultrasound elastography in the differential diagnosis of benign or malignant breast tumors has a high accuracy rate.
