Diagnostic and evaluation value of CT enterography in Crohn's disease
Objective To explore the diagnostic and evaluation value of CT enterography for Crohn's disease.Methods A total of 80 patients with clear diagnosis of small intestinal Crohn's disease admitted to Northern Jiangsu People's Hospital of Jiangsu Province from July 2021 to July 2023 were selected as the study subjects,and CT enterography was used for diagnosis.The diagnostic results of CT enterography,the examination results of the lesion site,the comparison of intestinal wall thickening between active and remission stages,the CT value of intestinal wall in the vein phase with or without wooden comb sign,intestinal wall thickness,stratified enhancement of intestinal wall,homogeneous enhancement of intestinal wall were analyzed.Results(1)CT enterography showed that 76 cases were diagnosed accurately,with a diagnostic accuracy rate of 95.00％(76/80).Specific symptoms included:intestinal stenosis,omental inflammation,abdominal abscess,intestinal wall stratification,increased and enhanced intestinal wall thickness,wooden comb sign,lymph node enlargement,fistula,etc;(2)The main lesion sites of CT small intestine imaging included:the distal end of the ileum,simple ileum,colon and ileum,jejunum and ileum,with the main site located at the distal end of the ileum(61.84％);(3)The intestinal wall thickness of Crohn's disease during the active phase was significantly greater than that during the remission phase(P＜0.05);(4)There were statistically significant differences in CT values,intestinal wall thickness,stratified enhancement and homogeneous enhancement of intestinal wall in the vein phase with or without the wooden comb sign(all P＜0.05).Conclusion CT enterography has a high diagnostic accuracy for Crohn's disease and can clearly display the condition of intestinal wall lesions in patients,providing important reference basis for clinical treatment.
