The Value of Non-enhanced MSCT Scanning in Diagnosis of Acute Appendicitis

Objective To explore the value of non-enhanced helical CT scanning and reconstruction in diagnosis of acute appendicitis preoperatively for the location and qualitation.Materials and Methods The imaging data including CT and reconstruction images of 100 patients with acute appendicitis confirmed by surgery and 100 patients without acute appendicitis were retrospectively analyzed.The study appearance includes the location,diameter,wall thickness,content of appendix and structure around the appendix.Results Among 100 patients with acute appendicitis,the appendix ware detected in 91 cases.Among 100 cases without acute appendicitis,the appendix were detected in 82 cases.The distribution of appendix in 2 groups showed no difference by statistically significant(P0.05).The diameter,wall thickness of appendix in 2 groups showed difference by statistically significant(P 0.01).The MSCT appearances of acute appendicitis includes enlarged appendix(88%),the fecalith(22%) and air(18%) in appendix,periappendicular exudative peritonitis(62%) and periappendicular abscess(14%).Conclusion MSCT is of significant value in diagnosis of acute appendicitis including the location and qualitation.It is helpful for the evidence of operative proposal.
