| 中文摘要: |
| 目的 观察高分辨MRI用于鉴别直肠原发癌与转移癌的价值。方法 回顾性分析41例直肠原发癌（原发组）及14例直肠转移癌（转移组），比较组间MRI表现并观察其鉴别效能。结果 组间受累肠管长度、肠壁增厚类型、区域淋巴结短径及数目，以及邻近脏器受侵、黏膜残留、同心圆征、直肠系膜拖尾征、直肠系膜筋膜（MRF）受累、MRF增厚伴强化及腹腔积液占比差异均有统计学意义（P均＜0.05），上述各参数用于鉴别的曲线下面积为0.721～0.890。结论 高分辨MRI对鉴别直肠原发癌与转移癌具有重要价值。 |

| Objective To observe the value of high-resolution MRI for differentiating primary and metastatic rectal cancer. Methods Totally 41 patients with primary rectal cancer and 14 cases of metastatic rectal cancer were retrospectively enrolled. MRI manifestations were compared between groups， and their differentiating efficacy was evaluated. Results Significant differences of the length of involved rectum，the type of intestinal wall thickening， the short diameter and number of regional lymph nodes， as well as the proportion of adjacent organ invasion， mucosal preservation， concentric circle sign， mesenteric tail sign， mesenteric fascia （MRF） involvement， MRF thickening and enhancement， also of peritoneal effusion were found between groups （all P＜0.05）， and the area under the curve of the above indexes was 0.721—0.890. Conclusion High-resolution MRI had important value for differentiating primary and metastatic rectal cancer. |
