摘要: 目的：探讨T2WI 3D-SPACE联合EPI DWI成像技术在直肠癌术前评估中的应用价值。方法：回顾性收集2018年1月1日至2019年8月30日于我院行直肠磁共振（MR）扫描的直肠癌患者36例纳入本组研究，扫描三方位高分辨T2WI序列、T2WI 3D-SPACE序列、EPI DWI序列。分别计算高分辨T2WI序列联合EPI DWI序列（A组）、T2WI 3D-SPACE序列联合EPI DWI序列（B组）对直肠癌T分期的敏感性、特异性及准确性，并采用McNemar检验比较两组序列总的T分期准确性有无显著性差异。结果：两组序列分别与术后病理结果对照，B组序列T1、T2期准确性稍高于A组序列，两组序列总的T分期准确性分别为68.75%和71.88%，差异无统计学意义（P>0.05）。结论：T2WI 3D-SPACE序列联合EPI DWI序列对直肠癌T分期的准确率与高分辨T2WI序列联合EPI DWI序列相比无统计学差异，可作为直肠癌MRI常规术前评估序列。

Abstract: Objective: To explore the value of T2WI 3D-SPACE combined with EPI DWI imaging in preoperative evaluation of rectal cancer. Methods: A total of 36 patients with rectal cancer who underwent MR scan from January 2018 to August 2019 were enrolled in this study. The scan protocol includes: three-dimensional highresolution T2WI sequences, T2WI 3D-SPACE and RS-EPI DWI sequence. The sensitivity, specificity and accuracy of T-staging of high-resolution T2WI combined with DWI(Group A sequences) and T2WI 3D-SPACE combined with DWI(Group B sequences) were calculated respectively. McNemar test was used to compare the accuracy of total T-staging between the two groups. Results: T staging of the two groups were compared with postoperative pathological findings. The accuracy in the T1 and T2 stages of the Group B sequences was slightly higher than the Group A sequences. The total T staging accuracy of the Group A and B sequences were 68.75% and 71.88% respectively. The difference was not statistically significant(P>0.05). Conclusion:The accuracy of T2WI 3D-SPACE sequence combined with EPI DWI sequence for T staging of rectal cancer is not statistically different from that of high-resolution T2WI sequence combined with EPI DWI sequence. Therefore, T2WI 3D-SPACE sequence can be routinely used for preoperative evaluation of rectal cancer.-
