多层螺旋CT小肠增强造影在诊断炎症性肠病中的价值研究

目的评估多层螺旋CT小肠增强造影（MSCTE）在诊断炎症性肠病（IBD）中的价值。方法回顾性分析45例IBD患者的病史资料,总结其MSCTE的影像学表现特点,并与常规结肠镜检查结果进行对比分析。结果 45例IBD患者中克罗恩病（CD）29例,溃疡性结肠炎（UC）16例。CD患者中,25例MSCTE有阳性发现,最常见的为肠道管壁增厚（21例,72.4%）及肠周间隙模糊伴渗出（9例,31.0%）;发现病变的部位以回盲部及末端回肠最多（44.8%）;MSCTE表现与结肠镜检查结果对比,前者发现的病变部位与后者完全吻合的有15例（51.7%）,前者发现空肠病变部位而后者无法发现的有10例（34.5%）。UC患者中,只有6例MSCTE有阳性发现,其中肠道管壁增厚亦最多见（5例,31.3%）;发现病变的部位以结肠居多（31.3%）;MSCTE表现与结肠镜检查结果对比,前者发现的病变部位与后者完全吻合的只有5例（31.3%）,而后者发现病变部位而前者未发现的却有11例（68.7%）。结论多层螺旋CT小肠增强造影对于CD的诊断价值较高。可通过发现小肠可能的病灶来弥补常规结肠镜检查的不足。MSCTE对于UC的诊断价值有限。

The Investigation of Multi-slice CT Enteroclysis in the Diagnosis of Inflammatory Bowel Disease

Objective To evaluate the value of multi-slice CT enteroclysis(MSCTE) in the diagnosis of inflammatory bowel disease(IBD).Methods Retrospectively analyze the case history of 45 patients with IBD,summarize the imaging features of MSCTE and compare to the colonoscopy results.Results 45 IBD patients included 29 cases of Crohn's disease(CD) and 16 cases of ulcerative colitis(UC).Among CD patients,positive features were found in 25 cases,of which the most common was thickened bowel wall(21 cases,72.4%) and blur ...
