To identify and evaluate profiles of US CT features associated with acute appendicitis.Consecutive patients presenting abdominal pain at the emergency department were invited to participate in this study. All underwent CT. Imaging known be appendicitis, an imaging diagnosis prospectively recorded by two independent radiologists. A final was assigned after 6 months. Associations between appendiceal a appendicitis evaluated logistic regression analysis.Appendicitis 284 942 (30%). appendicitis. created multivariable analysis. Of 147 thickened appendix, local transducer tenderness peri-appendiceal fat infiltration on US, 139 (95%) had On CT, 119 whom appendix completely visualised, thickened, enhancement, 114 (96%). When least these essential present or sensitivity 92% (95% CI 89-96%) 96% 93-98%), respectively.Most can categorised within few are made accurately.
