摘要
目的探究超声与磁共振(MRI)在乳腺良、恶性肿块中的诊断价值。方法对苏州市吴江区第一人民医院2012年1月至2014年6月122例患者129个乳腺肿块术前均行超声及MRI检查,回顾性分析超声及MRI检查结果,并与术后病理相比较。结果 129个乳腺肿块中,通过术后病理诊断为恶性病变37个,良性病变92个。MRI检查与超声检查对乳腺肿块诊断的真阳性率、准确率、阳性预测值差异无统计学意义(P>0.05);超声与超声联合MRI检查对乳腺肿块诊断的真阳性率、准确率、阳性预测值差异有统计学意义(P<0.05);MRI检查与超声联合MRI检查对乳腺肿块诊断的真阳性率、准确率、阳性预测值差异无统计学意义(P>0.05)。结论超声与MRI检查对乳腺良、恶性肿块的诊断均具有一定价值,超声价格低廉、操作简便,可用于对乳腺癌的筛查,而MRI对乳腺癌诊断的准确率比超声高,减少了误诊发生率,大大提高了诊断的真实性和可靠性,在经济条件允许的情况下值得临床开展应用。
Objective To evaluate the diagnostic value of ultrasonography and MRI in benign and malignant breast tumors.Methods 122 cases of patients（with a total of 129 breast tumors）were selected and detected by ultrasonography and MRI before surgery in the First People′s Hospital of Wujiang District,from January 2012 to June2014.The results of ultrasonography and MRI were retrospectively analyzed and compared with the postoperative pathological results.Results Among 129 breast tumors,there were 37 malignant lesions and 90 benign lesions,according to the postoperative pathological results.There was no significant differences of true positive rates,accuracies and positive predictive values between ultrasonography and MRI（P〉0.05）.The true positive rate,accuracy and positive predictive value of ultrasonography were significantly different from those of combined detection of ultrasonography and MRI（P〈0.05）,which of MRI were similar to those of combined detection of ultrasonography and MRI（P〉0.05）.Conclusion Both of ultrasonography and MIR had diagnostic value of benign and malignant breast tumors.Ultrasonography was cheap,simple,and good for the screening of breast carcinoma.The accuracy of MRI was higher than ultrasonography and helpful to reduce the misdiagnosis rate and improve the facticity and reliability of diagnosis,which should be carried out in clinic,if the economic conditions allowed.
