Özet
© 2021, Author(s).Background: Diagnosis of an inflamed appendix is commonly based on clinical, laboratory, and diagnostic imaging data. Ultra-sonography (US) is the leading diagnostic modality for these patients. However, an inconclusive US examination suggests the application of non-enhanced computed tomography (NECT). Objectives: This study aimed to compare US, NECT, and diffusion-weighted magnetic resonance imaging (DW-MRI) examinations for an accurate diagnosis of acute appendicitis with the rate of proven appendicitis by surgery. Patients and Methods: This retrospective study was performed on 70 patients, diagnosed with acute appendicitis between February 2018 and January 2020. The diagnostic accuracy of US, CT, and DW-MRI for acute appendicitis was examined in relation to the demographic and clinical variables. Results: Age and gender were not significantly associated with surgically proven appendicitis. However, the appendix diameter had a significant association with surgically proven appendicitis. All DW-MRI–positive patients with acute abdominal symptoms were surgically diagnosed with acute/subacute appendicitis (even those with < 6 mm in diameter). Based on the ROC curve analysis, the sensitivity and specificity of DW-MRI in predicting acute appendicitis was 100% and 90.90%, respectively. Conclusion: The appendix diameter was an important factor in diagnosing acute appendicitis. However, DW-MRI is an advanced technique that may exclude the need for the appendix diameter measurements.
