AIM: To assess the interobserver agreement of computed tomography (CT) reporting standards for chronic pancreatitis (CP). SUBJECTS AND METHODS: Retrospective analysis of CT of 47 patients (33 males and 11 females, age range 36 to 56 years) with CP who presented with abdominal pain (n = 41), steatorrhea (n = 37), and glucose intolerance (n = 31). The patients underwent CT study using a 16-multidetector CT scanner with a pancreatic protocol including a nonenhanced scan followed by pancreatic phase at 35 s and portal venous phase at 65 s after intravenous injection of nonionic contrast medium. Image analysis was performed by two radiologists according to reporting standards for CP. RESULTS: There was excellent interobserver agreement (84.8 %) between the two reviewers in CT reporting standards for CP (K = 0.80, 95 % CI 0.75-0.85, P = 0.001). There was good interobserver agreement for pancreatic duct (PD) caliber (K = 0.71, 95 % CI 0.56-0.87, P = 0.001), PD contour (K = 0.76, 95 % CI 0.61-0.91, P = 0.001), PD stricture (K = 0.070, 95 % CI 0.53-0.88, P = 0.001), and distribution of findings (K = 0.69, 95 % CI 0.51-0.86, P = 0.001). There was excellent interobserver agreement for intraductal calculi (K = 0.84, 95 % CI 0.68-0.98, P = 0.001), pancreatic calcifications (K = 0.86, 95 % CI 0.84-0.98, P = 0.001), and pancreatic diameter (K = 0.87, 95 % CI 0.75-0.99, P = 0.001). CONCLUSION: CT reporting standards for CP is a reliable method for diagnosis of patients with CP.
