Value of three-dimensional multi-slice spiral computed tomography imaging in the diagnosis and activity evaluation of Crohn's disease / 中国医师杂志

ABSTRACT

Objective To evaluate the diagnostic value of three-dimensional multi-slice spiral computed tomography (CT) imaging in Crohn's disease(CD) of small intestine and its active and remission stages.Methods The clinical and CT data of 34 patients with Crohn's disease confirmed by digestive endoscopy were retrospectively analyzed.According to whether the lesions were active,the patients were divided into active group (25 cases) and remission group (9 cases).The difference of CT signs between the two groups was compared.Chi square test was used to evaluate the diagnostic efficiency of CT three-dimensional imaging for polyps and their activity evaluation of Crohn's disease.Results The incidences of intestinal wall stratification,moderate enhancement,severe enhancement,ulcer,cellulitis,lymph node enlargement and wood comb sign in active group were higher than those in remission group (x2 =20.193,9.018,4.986,3.947,9.551,4.986,6.766,4.986 respectively,P ＜ 0.05).The incidence of intestinal wall monolayer thickening,non-enhancement,mild enhancement and abdominal abscess in remission group was higher than that in active group,with significant difference (x2 =15.092,13.768,25.336,16.996,P ＜0.05).while there were no significant difference between the two groups in the incidence of pneumoperitoneum,intestinal stenosis and enlargement (P ＞ 0.05).Conclusions Spiral CT three-dimensional reconstruction imaging can show the intestinal wall thickening,intestinal lesions and parenteral complications of Crohn's disease comprehensively,carefully and intuitively,and play an important role in guiding clinical treatment by evaluating the active and remission stages of CD.
