乳腺癌的影像学特征观察与分析

目的对乳腺癌的影像学特征进行观察与分析,为今后的临床治疗工作提供可靠的参考依据。方法抽取在2010年1月至2012年12月间我院与肇庆市第二人民医院收治的可疑早期乳腺癌临床患者病例90例,对其在术前分别展开钼靶、超声、钼靶与超声联合以及MRI检查,并将上述四种检查方法的检查结果同病理结果进行比较,而后对比分析各种检查方法的准确性、特异性、敏感性、阴性预测值、阳性预测值、假阳性率以及假阴性率。结果经统计,钼靶与超声联合检查和MRI检查结果的准确性、特异性、敏感性、阴性预测值、阳性预测值均较钼靶、超声单独应用明显提高(P<0.05),且假阳性率和假阴性率均得到了显著降低(P<0.05);而钼靶超声联合检查结果与MRI检查结果差异无显著统计学意义(P>0.05)。结论对于乳腺癌早期临床诊断而言,钼靶与超声联合的检查方法和MRI检查能够使诊断的准确性得到显著提高,为临床治疗方案的选择提供可靠的参考依据,值得推广应用。

Observation and Analysis of the Characteristics of the Breast Cancer Image

Objectlve To breast cancer imaging features were observed and analyzed, and provide a reliable basis for clinical treatment in future. Methods In the second people＇s hospital from 2010 January to 2012 December in our hospital and Zhaoqing city suspicious early breast cancer patients with clinical cases in 90 cases, the respectively, ultrasound, molybdenum target mammography combined with ultrasonic and MRI examination before operation, and the four methods of inspection findings and pathological results were comparison and contrast analysis, the accuracy of different examination methods, the specificity, sensitivity, negative predictive value, positive predictive value, false positive rate and false negative rate. Results The statistical results, mammography and ultrasound examination and MR/examination results of accuracy, specificity, sensitivity, negative predictive value, positive predictive value than mammography, ultrasound alone significantly increased （P〈0.05）, and the false positive rate and false negative rate were significantly decreased （P〈0.05）; and the difference of molybdenum targeted ultrasound examination results and the results of MR/were not statistically significant （P〉0.05）. Conclusion In breast cancer early diagnosis, marnmography and ultrasound examination and MRI examination can make the diagnosis accuracy is greatly improved, provide a reliable basis for the clinical treatment options, it is worthy of popularization and application.
