Core Tip

Core Tip: This retrospective study aims to determine the accuracy of detecting the presence and possible location of obstruction on computed tomography (CT) scenogram images of the abdomen, which can be used as the primary imaging method in the diagnosis of acute bowel obstruction, taking observer experience into account. The experienced observer had the highest sensitivity (83.33%), positive predictive value (94.59%), and diagnostic accuracy (80.43%) for detecting mechanical obstruction (MO). The diagnostic accuracy of the same observer in estimating the segmentation of a MO was 80.43%. These findings show that CT scenogram images alone can demonstrate high diagnostic accuracy and sensitivity in relation to years of experience in diagnosing ileus.
