Application of 64-Slice Spiral CT Reconstruction Technique in Diagnosis of Acute Appendicitis

Objective To investigate the effectiveness of 64-slice spiral CT reconstruction technique in diagnosis of acute appendicitis.Methods Retrospective analysis of 64-slice spiral CT scan images was performed on 60 patients who underwent abdominal 64-slice spiral CT scans and were confirmed through clinical pathology as acute appendicitis sufferers.After multi-planar and curve reconstruction of all the images in the workstation,observation and analysis of appendicitis were made on the size,morphology and surrounding changes.Results Among 60 patients with acute appendicitis,21 cases were found acute simple appendicitis,32 superlative appendicitis,5 appendiceal abscess,2 appendiceal perforation.Two kinds of features-direct and indirect features could be gained from 64-slice spiral CT findings.Direct features include thickened and enlarged appendicitis(diameter 6 mm),thickened wall of the appendicitis,appendicitis calculus.Indirect features included inflammation,abscess or inflammatory mass around the appendicitis,free intraperitoneal gas and swelling local lymph nodes.Conclusion Acute appendicitis had typical features in its CT iamges.Application of 64-slice spiral CT reconstruction techniques could have a better reveal of appendicitis and its surrounding circumstances,which significantly improved the diagnosis of appendicitis and was of great application value.
