Magnetic resonance imaging (MRI) was conducted in 21 patients with known or suspected colorectal mass lesions. Imaging was carried out at 1.5 T using Fast Low Angle Shot (FLASH) and fat-suppressed (T1FS) gadolinium enhanced sequences. The lesions studied included adenocarcinoma (n = 16), lipoma (n = 2), villous adenoma with foci of adenocarcinoma (n = 1), malignant melanoma (n = 1), and rectal lymphoma (n = 1). Correlation was made with surgical findings in 14 patients, 10 of whom had tumors resected. Bowel wall involvement, tumor size, and extension demonstrated on MR images was correlated with histopathology findings. No significant differences were found (p > 0.05) among those parameters when compared to MR information from T1FS images. Lymph nodes were demonstrated on MR images but distinction between benign and malignant nodes could not be made.
对21例已知或疑似结直肠肿块病变患者进行了磁共振成像（MRI）检查。成像在1.5T下使用快速低角度激发（FLASH）和脂肪抑制（T1FS）钆增强序列进行。研究的病变包括腺癌（n = 16）、脂肪瘤（n = 2）、伴有腺癌灶的绒毛状腺瘤（n = 1）、恶性黑色素瘤（n = 1）和直肠淋巴瘤（n = 1）。对14例患者的手术结果进行了相关性分析，其中10例患者的肿瘤被切除。MR图像上显示的肠壁受累、肿瘤大小和范围与组织病理学结果相关。与T1FS图像的MR信息相比，这些参数之间未发现显著差异（p > 0.05）。MR图像上显示了淋巴结，但无法区分良性和恶性淋巴结。
