To assess the interobserver agreement of computed tomography (CT) reporting standards for chronic pancreatitis (CP).
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.
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).
CT reporting standards for CP is a reliable method for diagnosis of patients with CP.
评估慢性胰腺炎(CP)计算机断层扫描(CT)报告标准的观察者间一致性。
回顾性分析 47 例(33 名男性和 11 名女性,年龄 36 至 56 岁)CP 患者的 CT 资料,这些患者表现为腹痛(n=41)、脂肪泻(n=37)和葡萄糖耐量异常(n=31)。患者采用胰腺协议进行 16 排多层 CT 扫描仪 CT 检查,包括非增强扫描,然后在静脉注射非离子型造影剂后 35 秒进行胰腺期扫描,65 秒进行门静脉期扫描。图像分析由两名放射科医生根据 CP 的报告标准进行。
两名观察者在 CP 的 CT 报告标准方面具有极好的观察者间一致性(84.8%)(K=0.80,95%CI 0.75-0.85,P=0.001)。在胰管(PD)口径(K=0.71,95%CI 0.56-0.87,P=0.001)、PD 轮廓(K=0.76,95%CI 0.61-0.91,P=0.001)、PD 狭窄(K=0.070,95%CI 0.53-0.88,P=0.001)和发现分布(K=0.69,95%CI 0.51-0.86,P=0.001)方面具有良好的观察者间一致性。在胰管内结石(K=0.84,95%CI 0.68-0.98,P=0.001)、胰腺钙化(K=0.86,95%CI 0.84-0.98,P=0.001)和胰腺直径(K=0.87,95%CI 0.75-0.99,P=0.001)方面具有极好的观察者间一致性。
CP 的 CT 报告标准是诊断 CP 患者的可靠方法。
