【摘要】：目的:评价单独使用乳腺X线摄影、单独使用高频超声检查技术在诊断乳腺伴钙化性病变的意义,并探讨将二者联合使用对疾病的检出是否有意义。方法:收集我院经乳腺X线摄影检查和高频超声检查,有钙化存在,经病理证实的乳腺钙化性病变患者122例,其中24例不可触及到微小病变术前行二维钩丝定位。采用全数字化SIMENS乳腺机进行乳腺X线摄影检查,观察记录乳腺钙化病灶的大小,位置,数目,形态和分布类型征象,综合分析诊断病变良恶性。采用GE LOGIQ 9彩色多普勒超声检查仪进行超声检查,多角度侧动探头以显示恶性钙化,然后行彩色多普勒血流成像(Color doppler flow imaging,CDFI)观察病变周边和内部的血流情况,综合分析病变判断其良恶性。应用SPSS 19.0软件包进行统计方法及数据处理,计数资料用X2检验(如果不满足X2检验条件,采用Fisher' S精确概率法),以P0.05为差异具有统计学意义。结果:122例乳腺伴钙化疾病患者病理诊断结果:乳腺X线摄影对乳腺钙化性疾病诊断的敏感性、特异性、阳性预测值、阴性预测值、漏诊率、误诊率、准确性分别为 85.3%、70.2%、82.1%、75.0%、29.8%、14.7%、79.5%;高频超声对乳腺钙化性疾病诊断的敏感性、特异性、阳性预测值、阴性预测值、漏诊率、误诊率、准确性分别为78.7%、66.0%、78.7%、66.0%、34.0%、21.3%、73.8%;二者联合应用分别为 94.6%、93.6%、95.6%、91.7%、6.4%、5.3%、94.3%。二者联合应用诊断的准确性高于乳腺X线或超声单独应用(P0.05)。结论:1.乳腺X线摄影通过钙化特征来鉴别乳腺良恶性疾病具有一定意义,通过彩色多普勒超声观察血流信号对诊断乳腺癌具有一定指导价值。2.乳腺X线摄影和高频超声的联合使用可以优势互补,对乳腺钙化性病变的诊断优于其单独诊断。3.二维钩丝定位可以提高乳腺微小病变手术的精确性。
[Abstract]:Objective: to evaluate the value of mammography alone and high frequency ultrasound alone in the diagnosis of breast lesions with calcification. Methods: collect mammography and high frequency ultrasound examination, calcification exists in our hospital. Twenty-two cases of calcified lesions of breast were confirmed by pathology, of which 24 cases were diagnosed as untouchable microlesions. All digital SIMENS mammography was used for mammography. The size, location, number, morphology and distribution of calcified breast lesions were observed and recorded. The diagnosis of benign and malignant lesions was analyzed. GE LOGIQ 9 color Doppler ultrasound instrument was used to detect malignant calcification. Then color doppler flow imaging (CDFI) was performed to observe the blood flow around and inside the lesion. SPSS 19.0 software package was used for statistical method and data processing, and the count data was tested by X2 test (if the condition of X2 test was not satisfied). Fisher's exact probability method is used. Results 122 cases of breast with calcification disease pathological diagnosis results: mammography for the diagnosis of breast calcification disease sensitivity specificity. The positive predictive value, the negative predictive value, the missed diagnosis rate, the misdiagnosis rate and the accuracy were 85.3% and 72.2%, respectively. The sensitivity, specificity, positive predictive value, negative predictive value, missed diagnosis rate, misdiagnosis rate and accuracy of high-frequency ultrasound in the diagnosis of calcified breast diseases were 78.7%, 66.0% and 78.7%, respectively. 66.0 and 34.0 and 21.3and 73.8; The combined use of the two methods was 94.6% and 93.6%, 91.7% and 5.3%, respectively. 94.30.The diagnostic accuracy of the combination of the two is higher than that of mammography or ultrasound alone (P0.05). Conclusion 1. Mammography has a certain significance in differentiating benign and malignant breast diseases by calcification. Color Doppler ultrasound observation of blood flow signal has a certain guiding value in the diagnosis of breast cancer. The combination of mammography and high-frequency ultrasound can complement each other. The diagnosis of calcified lesions of mammary gland is superior to that of single diagnosis.
