Abstract
Hepatobiliary disorders, including gallstones, cholecystitis, choledocholithiasis, and hepatic lesions, represent a major cause of morbidity. Early diagnosis is essential for optimal management. Ultrasonography (US) remains the primary imaging modality due to its safety, accessibility, and cost‐effectiveness, while computed tomography (CT) serves as a complementary tool for assessing disease extent and complications. The present study evaluates the diagnostic accuracy of US in comparison with CT for hepatobiliary disorders. Aim of the study was to assess the diagnostic accuracy, sensitivity, specificity, and agreement of ultrasonography in evaluating hepatobiliary disorders using CT as the reference standard, and to determine its reliability as a first‐line imaging modality. A prospective observational study was conducted in the Department of Radiology, including 75 patients with suspected hepatobiliary disease. All underwent abdominal ultrasonography using high‐resolution probes (1‐5 MHz curvilinear, 5‐12 MHz linear). Gallbladder wall thickness, stone size and mobility, common bile duct diameter, intrahepatic ductal dilatation, liver echotexture, and focal lesions were assessed. CT abdomen with contrast (triple‐phase protocol) was performed in selected cases for confirmation. Data were analyzed using SPSS version 26. Diagnostic indices were calculated, and agreement between modalities was assessed using Cohen’s kappa (κ) statistics. US demonstrated high diagnostic accuracy: gallstones (96%), acute cholecystitis (92%), CBD stones (92%), biliary dilatation (94%), liver parenchymal disease (91.6%), and focal hepatic lesions (90.6%). Cohen’s κ values indicated almost perfect agreement for gallstones (0.91), acute cholecystitis (0.85), and biliary dilatation (0.82), and substantial agreement for other conditions (κ = 0.73–0.78; p < 0.001). Ultrasonography provides a reliable, accurate, and noninvasive diagnostic approach for hepatobiliary diseases, demonstrating strong concordance with CT findings. While CT adds value in assessing lesion extent and complications, US remains the preferred initial imaging modality for evaluating hepatobiliary pathology, ensuring accurate diagnosis with minimal radiation exposure.
