摘　　要：目的探讨常规MRI联合弥散加权成像(DWI)对结肠癌性肠梗阻的诊断价值。方法对47例结肠癌患者行无肠道准备的常规MRI平扫及DWI检查,分析其成像的特点。结果 26例为结肠癌性肠梗阻,肠腔显著狭窄,呈"线样"或"细管样"征象,癌性狭窄移行段呈"肩样征";21例为单纯性结肠癌,狭窄近侧肠管无明显扩张。结论常规MRI联合DWI对结肠癌性肠梗阻具有较高的诊断价值,可作为结肠癌性肠梗阻的重要检查手段。Objective To explore the diagnostic value of conventional MRI combined with diffusion weighted imaging（DWI） in colon carcinoma union intestinal obstruction. Methods 47 patients with colon cancer were examined through conventional MRI combined with DWI without bowel preparation. Then the characteristics of colon cancer were analyzed. Results The lumens of 26 patients who were diagnosed as colon carcinoma union intestinal obstruction were obviously stenotic, which seemed like ＂line＂ or ＂tubule＂, and the transition segments were shown as ＂shoulder＂ characteristic. Other 21 patients were diagnosed as simple colon cancer with no obvious dilatation of proximal intestinal canal. Conclusion Conventional MRI combined with DWI has a high diagnostic value for colon carcinoma union intestinal obstruction and can be used as an important examination method.
