Methods The study used retrospective and cross-sectional methods to analyze the results of 117 patients who were taken photos of CT at E Hospital from February 2021 to November 2021. Results The most common age was over 50 years old and the average age was 40.1 20.8. The ratio of male female was 1 1.25. Locations of appendix right iliac fossa 69.2 posterior cecum 16.2 pelvis 12 subhepatic 0.9 1.7 in other places in the abdomen. The diameter of appendicitis was 10.48 2.5mm the min was 5mm the max was 18mm . The increase of diameter over 7mm accounted for 95.7 appendiceal wall thickness 3mm had 83.8 of patients and fat infiltration was seen in 88 of cases studied. Other signs fecal stones 35 fluid around appendix 7.7 Douglas fluid 3.4 right iliac fossa fluid 3.4 mesenteric lymphadenopathy 25.7 . The rate of appendix rupture diagnosed by CT accounted was 4.3 . The sensitivity accuracy and positive diagnostic value of multislice CT in the diagnosis of acute appendicitis were 97.4 96.6 and 99.1 respectively. Conclusion Multislice CT has a high value in the diagnosis of acute appendicitis. Keywords Acute appendicitis appendicitis CT scan MSCT. _ Corresponding author.
