To assess the reliability of a standardized reporting system of acute appendicitis at low-dose 320-rows CT. Retrospective analysis CT of 78 patients with pathologically proven acute appendicitis. The study was performed at a low-dose 320-rows CT. The image analysis was performed by 2 radiologists according to a standardized reporting system of acute appendicitis. There was an excellent overall of the inter-observer agreement of both observers for the standardized reporting system of acute appendicitis ( = 0.89, 95 % = 0.87-0.92, = 0.001). There was good inter-observer agreement for visualization of the appendix = 0.78, = 0.001), the tip diameter ( = 0.75, = 0.001), and a single wall thickness of appendix ( = 0.77, = 0.001). There was excellent inter-observer agreement for outer to outer wall diameter ( = 0.82, = 0.001), mucosal hyper-enhancement ( = 0.80, = 0.001), appendicolith ( = 0.86, = 0.001), gas in the appendix ( = 0.82, = 0.001), surrounding fat stranding ( = 0.81, = 0.001), focal cecal thickening ( = 0.85, = 0.001), peri-appendiceal air ( = 0.87, = 0.001), peri-appendicular fluid collection, phlegmon, or abscess ( = 0.82, = 0.001), and right ovary cyst ( = 0.83, = 0.001). we concluded that excellent reliability of a standardized reporting system of acute appendicitis in the adults using low-dose 320-rows CT. © 2019 The Author(s).
