摘要:
目的探究CT以及磁共振扩散加权成像(MRI-DWI)在食管癌术前评估中应用价值。 方法回顾性分析我院2017年8月~ 2019年7月期间收治107例食管癌患者相关资料,患者均接受手术治疗,手术前行CT以及MRI-DWI检查,术后行病理检查,分析CT与MRI-DWI判断T分期以及N分期价值,比较CT与MRI-DWI判断食管癌病变长度及其与实际病变长度相关性。 结果以病理诊断作为金标准,CT诊断T1、T2、T3及T4分期Kappa值分别为0.719、0.695、0.843、0.851,MRI-DWI诊断T1、T2、T3及T4分期Kappa值分别为0.958、0.948、0.925、0.921;CT诊断N分期Kappa值为0.806,MRI-DWI诊断N分期Kappa值为0.977;CT测定食管癌病变长度高于MRI-DWI测定以及标本实际病变长度(P < 0.05),MRI-DWI测定食管癌病变长度与标本实际长度比较,差异无统计学意义(P>0.05);Pearson相关性分析 结果显示,CT、MRI-DWI测定食管癌病变长度与实际样本病变长度相关性较高(r=0.816、0.991;P < 0.05)。 结论CT、MRI-DWI均可用于评估食管癌患者术前分期以及病变长度,但是MRI-DWI在术前分期与病变长度评估中价值更佳。 Abstract:ObjectiveTo explore the application value of CT and magnetic resonance diffusion weighted imaging (MRI-DWI) in preoperative evaluation of esophageal cancer. MethodsRelevant data of 107 patients with esophageal cancer who were treated at the hospital from August 2017 to July 2019 were retrospectively analyzed. All patients underwent surgical treatment. CT and MRI-DWI were performed before surgery, and pathological examinations were performed after surgery. Value of CT and MRIDWI in T staging and N staging were analyzed. Lengths of esophageal cancer measured by CT and MRI-DWI were compared with the actual length. ResultsUsing pathological diagnosis as the golden standard, Kappa values of CT in diagnosis of T1, T2, T3 and T4 stages were 0.719, 0.695, 0.843 and 0.851, which of MRI-DWI were 0.958, 0.948, 0.925 and 0.921. Kappa values of CT and MRI-DWI in diagnosis of N stage were 0.806 and 0.977, respectively. Length of esophageal cancer measured by CT was significantly larger than that by MRI- DWI. There was no significant difference between the length of esophageal cancer measured by MRI-DWI and the actual length (P>0.05). Pearson correlation analysis showed that lengths of esophageal cancer measured by CT and MRI-DWI were highly correlated with the actual length (r=0.816, 0.991, P < 0.05). ConclusionBoth CT and MRI-DWI can be used to evaluate preoperative staging and lesion length of patients with esophageal cancer, but MRI-DWI is better for preoperative staging and lesion length evaluation. -
