摘要
目的：对比分析超声弹性成像硬度评分与面积比值法对乳腺良、恶性肿块鉴别的诊断价值。方法回顾性分析2011年1月至2013年6月经病理证实的120例乳腺占位性病变患者（130乳）的超声影像学资料，其中恶性肿块62个，良性肿块68个，评估超声弹性成像硬度评分与面积比值法鉴别诊断乳腺良、恶性肿块的敏感性、特异性、准确率。结果（1）良性肿块超声弹性成像0～2分52例，3～4分16例；恶性肿块0～2分10例，3～4分52例。两组比较差异有统计学意义（χ^2＝11．55，P＜0．05）。（2）良性肿块平均面积比值为（1．09±0．37），恶性肿块为（2．28±1．68），两组比较差异有统计学意义（t＝6．22，P＝0．01）；（3）弹性成像硬度评分诊断乳腺恶性肿块灵敏度、特异度、准确率分别为83．87％、76．47％、80．00％，面积比值法分别为80.65％、75．00％、77．68％，两种方法联合检查分别为93．10％、93．55％、93．09％，联合检查具有明显优势，比较差异有统计学意义（均P＜0．05）。结论超声弹性成像硬度评分与面积比值法对鉴别乳腺良恶性肿块具有较高的应用价值，联合诊断准确率更高。
Objective To compare the value of hardness rating and area ratio method of ultrasound elastog-raphy in differential diagnosis of benign and malignant lesions.Methods ultrasound imaging data of 120 cases with breast lesions（130 breast）who were pathologically confirmed during the period from January 201 1 to June 2013 were retrospectively analyzed,there were 62 malignant tumors,68 benign tumors,the sensitivity,specificity,accuracy of hardness rating and area ratio method of ultrasound elastography in differential diagnosis of benign and malignant lesions were assessed.Results （1 ）The ultrasound elastography of 52 cases with benign tumor were 0 -2point, 16 cases were 3-4point,10 cases with malignant tumors were 0 -2point,52 cases were 3 -4point,the difference between two groups were statistically significant（χ^2 =11.55,P〈0.05）;（2）The average area ratio of benign tumor was （1.09 ±0.37）,malignant tumors was （2.28 ±1.68）,the difference between two groups were statistically signifi-cant（t =6.22,P=0.01）;（3）the sensitivity,specificity,accuracy of elastography hardness rating in diagnosis of malignant breast tumors were 83.87%,6.47%,80.00%,the area ratio method were 80.65%,75.00%,77.68%, joint inspection of two groups were 93.10%,93.55%,93.09%,joint inspection had obvious advantages,the differ-ence was statistically significant（all P〈0.05 ）.Conclusion Hardness rating and area ratio method of ultrasound elastography in differential diagnosis of benign and malignant lesions had higher value and higher diagnostic accuracy of combined.
