【摘要】 目的 总结多层螺旋CT(MSCT)在诊断Crohn肠病中的应用价值。方法 观察21例经临床、影像和病理3方面综合诊断为Crohn肠病的MSCT表现,分析其影像学特点。结果 21例均表现为多节段肠壁增厚,其中直、乙状结肠受累2例,系膜缘增厚明显有13节段,肠壁均有不同程度强化。肠壁溃疡3例,瘘管2例,肠内瘘1例,肠梗阻2例,肠旁蜂窝织炎6例,炎性包块或腹腔脓肿6例。肠系膜淋巴结肿大13例,系膜密度增高10例,继发肠间距增宽5例,系膜血管增粗、密集12例,梳子征8例。MIP和MPR技术更有助于全面显示病变。结论 MSCT对Crohn肠病肠壁的病变,肠外并发症及肠系膜、血管、淋巴结异常均有良好显示,并能判断病程,指导临床治疗,不失为一较好的影像检查方法。更多还原

【Abstract】 Objective To investigate the value of multi-slice spiral CT(MSCT) in diagnosis of Crohn enteropathy.Methods CT findings of twenty-one cases of Crohn enteropathy which were diagnosed by clinic in combination with radiology and pathology were analyzed.Results Multi-segment of intestinal walls thickened were seen in all cases,including two cases of rectal and sigmoid involved,mesenteric margins obviously thickened in 13 segments,and enhanced in varying degrees after administration of contrast medium.Other CT findings included:intestinal ulcers in 3 cases,fistula in 2 cases,enteral fistula in one,intestinal obstruction in 2 cases,para-intestinal phlegmon in 6 cases,inflammatory masses or abscesses in 6 cases,mesenteric lymphadenopathy in 13 cases,the density of mesentery increased in 10 cases,the secondary intestinal distance widened in 5 cases,mesenteric vessels thickened and concentrated intensive in 12 cases and the sign of combs in 8 cases.MIP and MPR were more conducive to show the focus of infection comprehensively.Conclusion MSCT can demonstrate exactly the lesions of intestinal walls of Crohn disease,and its complications,the abnormalities of parenteral mesenteric,blood vessels as well as lymph nodes,which is helpful in evaluating the course of the disease and guiding clinical treatment.更多还原
