目的:探讨CT小肠造影(CTE)联合肠系膜血管成像对克罗恩病的诊断价值。方法:回顾性分析22例经临床确诊的克罗恩病患者的CT资料,所有患者均行小肠CTE联合肠系膜血管重组检查,并采用多种图像后处理技术进行图像重组,由两位放射医师分析病变的影像学表现,并对比常规CTE和CTE结合肠系膜动脉CTA这2种方法对克罗恩病的定位诊断准确性。结果:2 2例克罗恩病患者中共33段小肠受累,采用常规CTE分组法正确诊断22段,联合CTA后正确诊断29段,两者比较差异有统计学意义(χ2=4.2,P<0.05)。CTE联合CTA法对各段小肠CD病变的定位诊断符合率均高于常规CTE。克罗恩病的主要CT表现:肠壁增厚(20/22),肠壁异常强化(17/22),黏膜强化(10/22),肠腔狭窄(10/22),直小血管增多(7/22),肠系膜淋巴结增生(4/22);肠外并发症主要为瘘管(1/22)、脓肿(1/22)和肾结石(1/22)等。结论:CTE联合CTA能准确显示克罗恩病的发生部位及病变的特点,定位诊断准确性优于常规CTE。
目的:探討CT小腸造影(CTE)聯閤腸繫膜血管成像對剋囉恩病的診斷價值。方法:迴顧性分析22例經臨床確診的剋囉恩病患者的CT資料,所有患者均行小腸CTE聯閤腸繫膜血管重組檢查,併採用多種圖像後處理技術進行圖像重組,由兩位放射醫師分析病變的影像學錶現,併對比常規CTE和CTE結閤腸繫膜動脈CTA這2種方法對剋囉恩病的定位診斷準確性。結果:2 2例剋囉恩病患者中共33段小腸受纍,採用常規CTE分組法正確診斷22段,聯閤CTA後正確診斷29段,兩者比較差異有統計學意義(χ2=4.2,P<0.05)。CTE聯閤CTA法對各段小腸CD病變的定位診斷符閤率均高于常規CTE。剋囉恩病的主要CT錶現:腸壁增厚(20/22),腸壁異常彊化(17/22),黏膜彊化(10/22),腸腔狹窄(10/22),直小血管增多(7/22),腸繫膜淋巴結增生(4/22);腸外併髮癥主要為瘺管(1/22)、膿腫(1/22)和腎結石(1/22)等。結論:CTE聯閤CTA能準確顯示剋囉恩病的髮生部位及病變的特點,定位診斷準確性優于常規CTE。

Objective:To investigate the value of CT enterography (CTE)and CTA in diagnosis of intestinal Crohn′s disease (CD).Methods:Retrospective analysis was made on 22 patients with CD,all of them underwent CTE and CTA examination and several reconstruction methods were used for image post-processing.The imaging characteristics of CD were analyzed by two radiologists,and the accuracy of CTE and CTE combined with CTA for localization diagnosis of CD was compared.Results:33 segments of small bowel in the 22 CD patients were involved,among which 22 segments were di-agnosed correctly by CTE,and 29 segments were diagnosed correctly by CTE combined with CTA,there was significant difference between the two methods(χ2= 4.2,P<0.05).The accuracy of the CTE combined with CTA method positioning in small bowel lesions are higher than the conventional CTE fractionation method.The major CT findings:intestinal wall thickening (20/22),obvious enhancement of intestinal wall (17/22)or mucosa (10/22),lumen stenosis (10/22),engorged vasa recta (7/22),mesenteric lymph nodes hyperplasia (4/22).Extra-enteric complications included fistulas (1/22),absces-ses (1/22),and renal stones (1/22).Conclusion:CTE combined with CTA can accurately display the main features of intes-tinal Crohn′s disease,and is superior to conventional CTE for the localization diagnosis of CD.
