【摘要】 目的探讨超声弹性成像对乳腺肿瘤的鉴别诊断价值。方法对98例107个乳腺结节进行超声弹性成像检查,并与病理结果比较。弹性成像按5分法分级。结果 107个乳腺结节,组织病理检查结果为良性结节68个,恶性结节39个。超声弹性成像评分≤3分(良性)67个结节,>3分(恶性)40个结节。良性结节超声弹性成像与病理诊断符合率为86.8%(59/68);恶性结节超声弹性成像与病理诊断符合率为79.5%(31/39)。以弹性成像评分>3分,并且弹性成像病灶面积与二维超声面积比≥1.5为恶性肿瘤诊断标准,诊断乳腺恶性病变的敏感性、特异性、准确性分别为79.4%、97.1%、和90.7%。结论弹性成像可有效评估组织硬度,定量参数面积比有助于乳腺肿块良恶性的鉴别。更多还原

【Abstract】 Objective To evaluate the value of elastosonography in the differential diagnosis of breast tumor.Methods Ninety-eight patients with 107 breast lesions were examined by elastosonography,and the result was compare with pathological result. The grading of elastosonography was done according to 5-score evaluating method. Results The histopathological examination showed that 61 benign lesions and 39 malignant lesions in 107 breast lesions. There were 67lesions( benign) with elastosonography score ≤3 and 40 lesions( malignant) > 3. The coincidence rate of elastosonography and histopathological examination in the diagnosis of benign lesions was 86. 8%( 59 /68),which was 79. 5%( 31 /39) in the diagnosis of malignant lesions. Based on the diagnostic standard for malignant lesions which was the elastosonography score > 3 and the ratio of lesion traced area in strain images versus in B-mode images ≥1. 5,the sensitivity,specificity and accuracy of elastosonograpy in the diagnosis of malignant breast lesions were 79. 4%,97. 1% and 90. 7%,respectively.Conclusion Elastosonography can evaluate the tissue hardness effectively,the area ratio of quantitative parameters might benefit the differential diagnosis of benign and malignant lesions.更多还原
