Abstract Objective To study the value of ultrasound combined with CT in the diagnosis of acute appendicitis.Methods A total of 60 patients with suspected appendicitis who received medical treatment in People's Hospital of Gongqingcheng City from September 2020 to October 2021 were selected as the research objects,and all of them completed the corresponding ultrasonic examination,CT examination and combined examination.The consistency,receiver operating characteristic(ROC) curve and imaging manifestations of different detection methods in the diagnosis of acute appendicitis were compared and analyzed.Results The detection accuracy of CT examination,ultrasound examination and combined examination were 88.33%,83.33% and 95.00% respectively,and the accuracy of combined detection was higher.The Kappa test consistency of CT examination,ultrasound examination and combined examination with pathological diagnosis of acute appendicitis was 0.691,0.556,0.864,and the Kappa test consistency of combined diagnosis was higher.The ROC curve was used to analyze the detection value of different detection methods.The results showed that the ROC curve of CT examination,ultrasound examination and combined examination in the diagnosis of acute appendicitis were 0.891,0.781,0.913,and the standard error was 0.028,0.064,0.031 respectively (P＜0.05).Among the main signs of acute appendicitis,the incidence of periappendicitis and peritonitis showed by combined detection were higher than those by CT and ultrasound examination,and the differences were statistically significant (P＜0.017).The average hospital stay was ranged from 5 to 20 d,with an average of (9.32±1.11) d.The hospitalization cost of patients ranged from 2 thousand to 15 thousand yuan,with an average of (5.11±0.71) thousand yuan.Conclusion Ultrasonic examination combined with CT diagnosis can improve the diagnostic accuracy.
