我们检查了16例胰腺癌诊断延迟至完整诊断CT的患者的20例诊断前CT。三名放射科医生独立审查了诊断前CT以及50名对照受试者的CT，包括无胰腺疾病（n=38）或CT上未见钙化的慢性胰腺炎（n=12）。审查员记录了胆管或胰管扩张、胰管中断、远端实质萎缩、轮廓异常和局灶性低衰减的存在。计算显著发现的频率、敏感性和特异性。进行Logistic回归分析。85%（17/20）的诊断前ct显示胰腺癌。胰脏癌患者有显著性差异(p
We examined 20 prediagnostic CTs from 16 patients for whom the diagnosis of pancreatic cancer was delayed until full diagnostic CT was performed. Three radiologists independently reviewed the prediagnostic CTs along with 50 CTs of control subjects, including patients without pancreatic disease (n=38) or with chronic pancreatitis without calcification visible on CT (n=12). The reviewers recorded the presence of biliary or pancreatic ductal dilation, interruption of the pancreatic duct, distal parenchymal atrophy, contour abnormality and focal hypoattenuation. Frequency, sensitivity and specificity of the significant findings were calculated. Logistic regression analysis was performed. Findings indicative of pancreatic cancer were seen on 85% (17/20) of the prediagnostic CTs. Patients with pancreatic cancer were significantly (p
