乳腺钼靶超声和磁共振检查评估乳腺癌大小的准确性分析

目的分析乳腺钼靶、超声和磁共振检查评估乳腺癌大小的准确性。方法选择45例浸润性乳腺癌患者为研究对象,术前分别行乳腺钼靶、超声及磁共振检查,并且与术后切除的病理标本进行对比,分析其对预测乳腺癌大小的准确性。结果磁共振检查对病灶的检出率明显高于检查对肿瘤大小的诊断准确性检查,差异有统计学意义(P<0.05)。乳腺钼靶、超声及磁共振回归系数分别为-0.113、0.289和0.238,其中磁共振评估乳腺癌大小诊断标准误最低,为0.087。结论磁共振对乳腺癌检出率高,并且对肿瘤大小测量的准确度明显优于超声及乳腺钼靶,可以作为患者手术评估的依据。

Accuracy study of mammography,ultrasound and magnetic resonance imaging on size evaluation of breast cancer before operation

Objective To investigate the accuracy of mammography,ultrasound and magnetic resonance imaging（MRI） in measurement of breast cancer size.Methods Fourty-five patients with invasive breast cancer were enrolled as the research object and mammography,ultrasound and MRI were performed preoperation.They were compared with the pathological specimens after resection.The accuracy of three methods for predicting breast cancer size were compared.Results Lesions detection rate of MRI was higher than that of the other two methods（P 〈 0.05）;Coefficients of mammography,ultrasound and MRI regression were-0.113,0.289 and 0.238,respectively.The MRI assessment of breast cancer diagnosis standard error of minimum size is 0.087.Conclusion Detection rate of breast cancer by MRI were the highest,and the tumor size measurement accuracy was better than ultrasound and mammography,can be used as the basis for assessment of patients with operation.
