目的：探讨磁共振结肠造影（ MRC）检查的临床应用价值。方法：收集167例结肠病变患者的MRC资料，总结其影像表现特点，并将MRC诊断结果与肠镜活检或手术病理结果进行对比分析。所有病例行肠道准备，经肛门注入生理盐水1200～1800 ml后，行多方位、多序列MR扫描及增强扫描。结果：167例患者MRC诊断正确147例，误诊15例，漏诊5例。 MRC诊断的准确率88．02％。结肠恶性肿瘤的MRC主要征象为肠壁局限性增厚或软组织肿块，多伴有肠腔狭窄；结肠良性肿瘤多表现为结节或肿块，边缘较光整；结肠炎性病变MRC表现为不均质肿块或肠壁广泛增厚，境界不清。结论：高质量的MRC图像对结直肠病变的检出及定性诊断有较高的准确性，对临床诊断及治疗具有重要的指导意义。

Objective:To explore the clinical application of MR colonography ( MRC) .Methods:Multi-planar , multi-sequence and contrast -enhanced MRI scanning were performed in 167 patients proved by colonoscopy or surgical pathology .Intestinal canal preparation should be done before all the examinations , and then infused with 1200~1800ml physiological saline immediately before study by anus .MRI diagnosis and im-age features were compared with colonoscopy or surgical pathology results .Results:Among the 167 patients with MR, 147cases were correctly diagnosed , misdiagnosis in 15 cases, missed diagnosis in 5 cases.The diagnostic accuracy of MR colonography was 88.02%.MR major signs of colon malignancy were a localized thickening of the bowel wall , soft tissue mass, associated with intestinal stricture;Colon benign tumors performed as nodules or masses with finishing edge;Colitis lesions showed a lump or widely thickening of intestinal wall .Usually its boundary was not clear and the signal was uneven .Conclusions:High quality magnetic resonance image has a higher accuracy of detection and qualitative diagnosis of colorectal lesions , which can provide important guiding significance for clinical diagnosis and treatment .
