| 摘 要： | 目的:探讨多层螺旋CT(MDCT)Crohn病影像特点及诊断价值。方法:对我院经病理证实的14例肠道Crohn病患者的MDCT影像特点进行回顾性分析。结果:所有病例均有跳跃性肠壁增厚,8例表现为肠壁环形增厚,同时伴有粘膜强化和分层形成"靶征"及"双晕征";有11例表现为增厚肠壁分层消失,增强不明显,肠壁厚度多在5～11mm。4例表现为病变段肠管周围肠系膜水肿及增厚,蜂窝织炎,其中并发脓肿1例。7例表现为肠系膜淋巴结肿大。有3例表现为肠系膜血管增多增粗形成"梳征"。其中"靶征"、"双晕征"及"梳征",均提示与病变活动度相关。结论:MDCT不但能准确显示Crohn病病变部位、肠外病变,还能区分活动性与非活动性病变。MDCT可作为Crohn病首选影像学检查方法。
