【摘要】：目的：1.探讨超声弹性成像在乳腺癌中的鉴别诊断价值。2.比较超声弹性成像、常规超声、钼靶及弹性超声与常规超声技术联合诊断这四种检查模式的差异。3.探讨超声弹性成像对不同大小的乳腺病灶的临床应用价值,以进一步评估其对小乳癌的筛查能力。方法：本研究对象为2013年10月至2014年10月在石河子大学医学院第一附属医院普外二科105名患者(110例病灶)乳腺病灶,术前均行超声弹性成像、常规超声及钼靶检查,术后进行病检对比,对上述结果进行统计学分析。再将这110例乳腺病灶按其长径大小分为2组,Ⅰ组(长径≤2 cm)66个和Ⅱ组(长径2 cm)44个,比较UE技术下两组的诊断价值。结果：1.肿块病理结果经病理证实的110个乳腺病灶中,良性62例,恶性48例。2.超声弹性成像诊断乳腺癌的灵敏度、特异度、准确度、阳性预测值及阴性预测值分别为91.67%,70.97%,80.00%,70.97%,91.67%。常规超声分别为81.25%,74.19%,77.27%,70.91%,83.64%。超声弹性成像联合常规超声进行筛检时的灵敏度、特异度、准确性、阳性预测值及阴性预测值分别为91.67%,87.10%,89.10%,84.62%,93.10%。钼靶分别为77.08%,69.35%,72.73%,66.07%,79.63%。3.上述四种检查方法ROC曲线下面积分别为0.874,0.777,0.894,0.732。面积均在0.7-0.9之间,其对鉴别乳腺癌有一定的价值。四种方法在诊断乳腺癌时,灵敏度：联合诊断、弹性超声单独诊断及常规超声单独诊断均高,差异无统计学意义(P0.05)。特异度：联合诊断高于单独诊断,与超声弹性成像、钼靶相比差异有统计学意义(P0.05)。准确性,联合诊断较单独诊断均高,差异均有统计学意义(P0.05)。4.超声弹性成像诊断Ⅰ组(长径≤2cm)的阴性预测值为97.22%,高于同方法诊断Ⅱ组(长径2 cm),差异有统计学意义(P0.05),余指标差异无统计学意义(P0.05)。结论：1.UE是常规超声、钼靶检查的一种有益补充,UE在乳腺癌诊断中具有良好应用前景。2.UE评分、常规超声及钼靶对乳腺良恶性病灶诊断均有一定价值,UE评分法准确度略高于常规超声,但二者差异无统计学意义,联合诊断能够提高诊断符合率。3.病灶大小对UE诊断的灵敏度、特异度影响不大,但阴性预测值会受其影响。
[Abstract]:Objective 1. To investigate the value of ultrasonic elastic imaging in differential diagnosis of breast cancer. The difference of the four diagnostic modes between molybdenum target and elastic ultrasound combined with conventional ultrasound. 3. To explore the clinical application value of ultrasonic elastic imaging in breast lesions of different sizes. Methods: from October 2013 to October 2014, 105 patients were enrolled in the general and second department of the first affiliated Hospital of Shihezi University. 110 lesions) breast lesions. The results were statistically analyzed after operation. The 110 cases of breast lesions were divided into two groups according to their length and diameter. Group 鈪，
