Background/Aims: The purpose of this prospective study was to evaluate the efficacy of spiral-CT for the identification of portal venous, superior mesenteric artery and celiac trunk infiltration in the staging of pancreatic (n = 29) and periampullary (n = 6) cancers. Materials and Methods: All patients were examined by contrast enhanced spiral-CT using a total volume of 240 mi contrast medium i.v. With a slice thickness of 5 mm and a table increment of 7mm/sec a overlapping data set, representing a total volume of 21 cm, was covered. The images were reconstructed in 4 mm intervals. In 28 patients the spiral CT results were correlated with surgical findings. Results: Regarding portal venous infiltration spiral-CT had a sensitivity of 91% (10/11), a specifity of 9.4% (16/17), a positive predictive value of 91% (10/11), a negative predictive value of 94% (16/17) and, an overall accuracy of 92,8% (26/28). Spiral CT correctly identified arterial involvement in 5 patients, and no false negative result compared to surgical findings was observed. Conclusions: These results indicate that spiral-CT reliably verifies occlusion, stenosis and encasement of the major peripancreactic vessels caused by pancreatic cancer.
