Abstract:

目的:探讨超声和热层析成像对乳腺导管内原位癌(DCIS)的诊断效果,以及不同医院的两种影像学方法之间的诊断效能差异。方法:回顾性分析2014年1月-2017年3月在武汉大学人民医院和四川大学华西医院经病理确诊为DCIS的病人以及同期良性对照病例,并根据入组医院不同分为N1和N2组,分别纳入73、76例病人,收集所有病人的超声及热层析资料进行对照研究。结果:149例病人中热层析诊断的灵敏度为85.8%、特异度98.75%、准确率为92.6%,均优于超声,有统计学意义(P=0.000)。超声联合热层析检出效能相对于单独热层析检查没有体现显著优势。对于两组间比较,N1组超声诊断灵敏度优于N2组(69.7%vs 44.4%,χ2=4.468,P=0.035),而热层析成像检出灵敏度、特异度、准确率均无统计学差异。结论:热层析成像在乳腺DCIS疾病中的检出效果明显优于超声,且不同于超声对于操作者经验与能力的依赖性,热层析成像可以比较客观的做出诊断,为DCIS的早期筛查与诊断提供了新的选择
