目的:探讨结直肠黏液腺癌的MRI表现。方法:回顾性分析经病理证实为结直肠黏液腺癌的32例患者的临床资料和MRI图像,分析病灶位置、长度、肠壁增厚类型和厚度、MRI信号特点、强化方式和T2WI高信号区比例。结果:32例结直肠黏液腺癌中,5例位于升结肠,1例位于降结肠,4例位于乙状结肠,22例位于直肠。肿瘤长度从3.4~15.7cm,平均长度5.7cm,病变肠壁厚度从0.6~3.1cm,平均厚度1.9cm。32例肿块的T2WI图像上均可见到特征性的高信号区,23例病灶的高信号区超过肿瘤面积的50%。结论:结直肠黏液腺癌的MRI表现具有一定特征性,有助于提高诊断准确性。
Objective: To investigate the MRI findings of colorectal mucinous adenocarcinoma. Methods: The clinical data and MRI images of 32 patients with histologically confirmed colorectal mucinous adenocarcinoma were retrospectively analyzed. The location and length of the lesion, the type and thickness of the thickening of the intestinal wall, the characteristics of the MRI signal, the enhancement mode and the T2WI high signal area proportion. Results: Of the 32 colorectal mucinous adenocarcinomas, 5 were in the ascending colon, 1 in the descending colon, 4 in the sigmoid colon, and 22 in the rectum. Tumor length from 3.4 ~ 15.7cm, the average length of 5.7cm, lesion wall thickness from 0.6 ~ 3.1cm, the average thickness of 1.9cm. The characteristic high signal area was found on T2WI images in 32 cases, and the high signal area in 23 cases exceeded 50% of the tumor area. Conclusion: The MRI findings of colorectal mucinous adenocarcinoma have certain characteristics, which can help improve the diagnostic accuracy.
