摘要
目的探讨超声弹性应变率比值法(UESR)对良性、恶性乳腺肿块鉴别诊断的价值。方法对95例乳腺肿块患者共122个病灶(良性72个,恶性50个)进行二维超声(2D-US)及超声弹性成像(UE)检查,同时做出2D-US及UE评分,获得UE成像图后,测量病灶与周围组织的UESR,并与术后病理进行对照。结果 UESR、UE评分法、2D-US评分法对诊断乳腺肿块的准确性分别为89.3%、86.7%、86.1%,特异性分别为83.3%、81.9%、77.8%,敏感性分别为98.0%、94.0%、98.0%。UESR的诊断准确性高于2D-US评分法(P<0.05),也高于UE评分法(P<0.05)。结论 UESR对乳腺肿块良恶性鉴别具有较高的诊断价值,为UE检查提供更为客观的诊断依据。
Objective To investigate diagnosis value of ultrasonic elastography strain ratio measure method for differentiating benign and malignant breast solid lesions. Methods Ninety-five patients with 122 lesions（72 benign, 50 malignant）were included in the study. The elastography strain ratio of the lesions could be automatically measured by ultrasonic machine, and simultaneously the lesions were scored with two-dimensional ultrasound （2D-US）scoring method and ultrasonic elastography respectively, and then the three methods were contrasted with pathological diagnosis. Results The accuracy of elastography strain ratio method, improved 5-scoring system in ultrasonic elastography and 2D-US scoring method were 89.3% ,86.7% ,86.1% ,the specificity were 83.3% ,81.9% ,77.8% , and the sensitivity were 98% ,94% , 98% , respectively. The accuracy of elastography strain ratio measure method was higher than those of ultrasonic elestography and 2D-US scoring method （ P 〈 0.05 ）. Conclusion Elastography strain ratio has higher diagnosis value for differentiating breast benign and malignant solid lesions, providing more objective diagnosis basis for UE.
