【摘要】 目的探讨高频超声、1.5T磁共振(MRI)对乳腺癌的诊断价值。方法回顾性分析我院2013年1月-2015年4月经手术病理证实50例乳腺癌患者影像学资料,观察高频超声、MRI影像学表现,同时与手术病理结果比较,分析高频超声、MRI单独、联合诊断正确率。结果以手术病理结果为金标准,高频超声诊断乳腺癌正确率为84.0%,MRI诊断正确率为92.0%,高频超声+MRI诊断正确率为98.0%。高频超声+MRI诊断正确率明显高于高频超声检查,差异有统计学意义(P<0.05)。结论1.5T MRI诊断乳腺癌正确率比高频超声高,高频超声+MRI检查能明显提高乳腺癌诊断准确率,临床值得推广。更多还原

【Abstract】 Objective To investigate the diagnostic value of high frequency ultrasound and 1.5T magnetic resonance imaging(MRI) in breast cancer. Methods The imaging data of 50 cases of patients with breast cancer confirmed by operation and pathology during January 2013 to April 2015 were retrospectively analyzed. The high frequency ultrasound and MRI imaging findings were observed and were compared with surgical and pathological results. The accuracies of high frequency ultrasound, MRI alone and combined diagnosis were analyzed. Results With the surgical and pathological results as the gold standard, the dianostic accuracy of high frequency ultrasound in breast cancer was 84.0% while of MRI was 92.0% and of the combination of the two was 98.0%. The dianostic accuracy of high frequency ultrasound combined with MRI was significantly higher than that of high frequency ultrasound and the difference was statistically significant(P<0.05). Conclusion The accuracy of 1.5T MRI in the diagnosis of breast cancer is higher than that of high frequency ultrasound. High frequency ultrasound combined with MRI can significantly improve the dianostic accuracy in breast cancer. In clinic, it is worthy of promotion.更多还原
