摘要 目的:探讨18氟-氟代脱氧葡萄糖正电子发射计算机断层扫描(18F-FDG PET/CT)在食管癌术前T、N分期中的应用价值。方法:选取100例行手术治疗的食管癌患者作为研究对象,术前均采用常规螺旋CT和18F-FDG PET/CT扫描评估T、N分期,以术后病理分期为金标准,比较常规CT和18F-FDG PET/CT检测食管癌分期的一致性和诊断价值。结果:经术后病理确诊,T1期16例,T2期27例,T3期35例,T4期22例;N0期52例,N1期48例。18F-FDG PET诊断食管癌T、N分期的Kappa值分别为0.741、0.780,常规CT诊断T、N分期的Kappa值分别为0.674、0.519;18F-FDG PET与常规CT对T分期的诊断符合率分别为81.0%、76.0%,差异无统计学意义(P>0.05);18F-FDG PET诊断食管癌对N分期的诊断符合率为89.0%,明显高于CT诊断的76.0%,漏诊率(8.3%)明显低于常规CT(25.0%),差异均有统计学意义(P<0.05);18F-FDG PET误诊率(13.5%)与常规CT(23.1%)比较,差异无统计学意义(P>0.05)。结论:18F-FDG PET/CT对食管癌患者术前T、N分期的诊断结果与病理诊断一致性高,且对N分期的诊断价值显著高于常规CT。
