Abstract    Objective    To discuss the application value of quantitative assessment of vascular invasion by pancreatic carcinoma with multi-slice spiral CT (MSCT). Methods    The essay analyzed 22 cases of pancreatic carcinoma admitted between August 2009 and June 2010 in China-Japan Union Hospital of Jilin University. They had been assessed prospectively and quantitatively with 320-slice spiral CT. Compared the CT scans results with operations, the diagnosis value of MSCT for pancreatic carcinoma was evaluated. Results    For the assessment of vascular invasion with MSCT, the sensitivity was 91.2%, and the specificity was 98.7%, and accuracy was 96.4%. When the length and the distance between the invaded vessel and vessel branches were measured, only two vessels were not correctly measured by MSCT. Conclusion    MSCT has high accuracy of evaluating the vascular invasion by pancreatic carcinoma, so that it can quantize the degree and range of invaded vessel correctly and it can provide important reference value for diagnosing and treating pancreatic carcinoma.
