摘　　要：目的探究磁共振成像(MRI)T1加权成像(T1WI)、T2加权成像(T2WI)、弥散加权成像(DWI)多序列扫描指导食管癌T分期的价值。方法回顾分析东台市人民医院2020年7月至2023年7月收治的102例食管癌患者病例,所有患者均接受手术治疗,术前接受MRI-T1WI、T2WI、DWI多序列扫描,术后获得完整病理学结果。以病理学结果分析MRIT1WI、T2WI、DWI多序列扫描判断患者T分期的效能,获取表观弥散系数(ADC)与患者T分期的相关性分析。结果MRI-T1WI、T2WI、DWI多序列检查对患者术前T分期T1~T4期判断准确率分别为94.74%、88.89%、96.08%、100.00%,不同T分期间判断准确率无明显差异(P>0.05),总准确率为94.12%,与病理结果一致性良好(Kappa值=0.935,P<0.001);不同T分期患者ADC值比较存在差异(P<0.05);Pearson相关系数结果显示:ADC值与患者T分期呈负相关(P<0.05)。结论MRI-T1WI、T2WI、DWI多序列扫描指导食管癌T分期有较高准确率,ADC值有潜力作为食管癌患者T分期预测指标。Objective To explore the value of magnetic resonance imaging(MRI)T1 weighted imaging(T1WI),T2 weighted imaging(T2WI)and diffusion weighted imaging(DWI)multi-sequence scans on guiding T staging of esophageal cancer.Methods A retrospective analysis was performed on 102 patients with esophageal cancer in Dongtai People’s Hospital from July 2020 to July 2023.All patients received surgical treatment.Preoperative MRI-T1WI,T2WI and DWI multi-sequence scans were performed,and complete pathological results were obtained after surgery.The pathological results were used to analyze the efficiency of MRI-T1WI,T2WI and DWI multi-sequence scans on judging T staging of patients,and the correlation between apparent diffusion coefficient(ADC)and T staging of patients was obtained.Results The accuracy rates of MRI-T1WI,T2WI and DWI multi-sequence examinations for preoperative T stage T1-T4 were 94.74%,88.89%,96.08%and 100.00%respectively.There was no significant difference in the accuracy rate of judgment between different T stages(P>0.05),and the total accuracy rate was 94.12%,which was in good consistency with the pathological results(Kappa=0.935,P<0.001).There was a difference in ADC value among patients with different T stages(P<0.05).Pearson correlation coefficient results showed that ADC value was negatively correlated with T staging(P<0.05).Conclusion MRI-T1WI,T2WI and DWI multi-sequence scans have a high accuracy rate in guiding T staging of esophageal cancer,and ADC value has the potential to be used as a predictor of T staging in patients with esophageal cancer.
