Value of multidetector ct in preoperative assessment of the vascular invasion in pancreatic adenocarcinoma

SUMMARY

Object: The purpose of this study is to assess the accuracy of multidetector computed tomography (MDCT) in preoperative determination of the vascular invasion in pancreatic adenocarcinoma.

Materials and methods: Multidetector computed tomography, surgery, and pathological results of 39 patients with pancreatic adenocarcinoma were evaluated retrospectively. MDCT findings were compared with surgical findings to determine the sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), and accuracy of MDCT in determining the vascular invasion.

Results: 39 patients (21 males, mean age: 58,8 years) underwent surgery. The sensitivity, specificity, PPV, NPV, and accuracy of MDCT in determining the vascular invasion of pancreatic adenocarcinomas were 88,9%, 96,9%, 86,5%, 97,5% and 95,9% respectively.

Conclusion: The accuracy of MDCT is high in preoperative determination of the vascular invasion in pancreatic adenocarcinoma.
