【摘要】：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:22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,P0.05)。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。
[Abstract]:Objective: to evaluate the diagnostic value of CT enterography combined with mesenteric angiography in Crohn's disease. Methods: Ct findings of 22 patients with Crohn's disease were retrospectively analyzed. All the patients underwent CTE combined with mesenteric vascular reorganization examination. The imaging findings of Crohn's disease were analyzed by two radiologists, and the accuracy of conventional CTE and CTE combined with mesenteric artery CTA in the diagnosis of Crohn's disease was compared. Results in 22 cases of Crohn's disease, 33 segments of small intestine were involved. 22 segments were correctly diagnosed by routine CTE grouping method, and 29 segments were correctly diagnosed after combined with CTA. There was a significant difference between the two groups (蠂 ~ 2 ~ (2) ~ (2) ~ (2) ~ (2) ~ (2)) P _ (0.05). CTE combined with CTA was higher than that of conventional CTE in the diagnosis of small intestinal CD lesions. The main CT findings of Crohn's disease were thickening of intestinal wall by 20 / 22, abnormal enhancement of intestinal wall by 17 / 22 / 22, mucosal enhancement by 10 / 22 / 22, stenosis of intestinal cavity by 10 / 22 / 22, increase of small vessels by 7 / 22, hyperplasia of mesenteric lymph nodes by 4 / 22; extraintestinal complications were mainly fistula 1 / 22, abscess 1 / 22) and kidney stone 1 / 22). Conclusion: the specific location and pathological features of Crohn's disease can be accurately demonstrated by CTA and the accuracy of localization is superior to that of conventional CTE.
