对31例胰腺癌和其它胰腺病变术前CT误诊和漏诊病例进行回顾性分析。结果误诊25例，其误诊率为44．0％（11／25）。主要原因：一是CT表现不典型；二是对某些CT征象认识不足以及分析欠全面。漏诊6例，主要为胰头部直径≤3cm的小胰头癌。通过对误诊、漏诊原因的分析，作者认为，改进检查技术，如采用薄层连续动态CT扫描，结合临床资料对CT征象作全面分析及综合多种影像学方法优势，可减少误诊、温沙机率。
A retrospective analysis of misdiagnosis and missed diagnosis of preoperative CT of 31 pancreatic and other pancreatic lesions was performed. Results 25 cases were misdiagnosed and the misdiagnosis rate was 44.0% (11/25). Main reasons: First, the CT manifestation is not typical; second, the lack of understanding of certain CT signs and the lack of comprehensive analysis. Missed 6 cases, mainly small pancreatic head cancer with a pancreatic head diameter ≤ 3cm. Through the analysis of misdiagnosis and missed diagnosis, the author believes that improved inspection techniques, such as thin-layer continuous dynamic CT scan, combined with clinical data for comprehensive analysis of CT signs and comprehensive imaging methods can reduce misdiagnosis and temperature .
