Application Value of Ultra-micro Blood Flow Imaging Technology in Evaluating the Activity of Intestinal Crohn's Disease
Objective:The purpose of this study is to explore the application value of super microvas-cular imaging,(SMI)in evaluating the activity of intestinal Crohn's disease(CD).Methods:From April 2022 to August 2023,60 patients diagnosed as Crohn's disease were selected from outpatient or inpatient treatment in the Department of Gastroenterology and Pediatrics of Jiangmen Central Hospital.According to the random number table method,they were randomly divided into reference group and control group with 30 cases in each group.Patients in the reference group received SMI technique to evaluate the blood flow of the diseased intestinal wall,while patients in the control group received PDI technique to evaluate the blood flow of the diseased intestinal wall.Results:In the reference group,the intestinal morphology of CD lesions was significantly higher than that in the control group(t=4.762,P＜0.05),and the intestinal size of CD lesions was significantly smaller than that in the reference group(t=5.192,P＜0.05).The scores of intestinal wall blood perfusion and intestinal integrity in the reference group were higher than those in the control group(x2=4.702,3.852,P＜0.05),and the peak velocity and volume flow of blood in the refer-ence group were also higher than those in the control group(t=4.376,5.376,P＜0.05).The degree of intes-tinal activity(CDAI score)and inflammation(SES-CD score)in the reference group were lower than those in the control group(t=4.269,4.059,P＜0.05).The intestinal vascular density in the reference group was significantly higher than that in the control group(t=12.127,P＜0.05).Conclusion:The results of this study show that the super microvascular imaging(SMI)is more accurate and reliable than the power Dop-pler imaging(PDI)in evaluating the pathological activity of intestinal Crohn's disease,and it can provide more clinical application value for evaluating the pathological activity.
