胰腺癌CT临床分析(附31例报告)

Clinical analysis of pancreatic carcinoma with CT scan (A report of 31 cases)

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。

To differentiate poncreatic carcinoma from mimicking lessons through a retrospective analysis of 31 cases. Results :Out of to-tal 25 cases,reciprocal misdiagnosis of pancreatic carcinoma and chronic pancreatitis were 11/25 (44.0%). We attributed the above mainly to: (1)presenting atypical CT appearances; (2)lack of knowledge about certain CT appearances and lack of compre-hensive analysis of CT appearances. We also missed 6 pancreatic carcinomas which were mostly situated in the head of pancreaswith a diameter≤3 cm. Conclusion: Through analysis of misdiagnnd and missed cases we suggested that the following steps betaken to minimized the chance of mlscliagnosis: (1)to improve study techniques, for example, use thin-section dynamic scan; (2)acornprehensive study of CT signs with correlation with clinicaI information; (3)combination of multiple imaging medalities.
