Abstract:
Objective To evaluation the application value of two-phase enhanced spiral CT in pancreatic adenocarcinoma. Methods Two-phase enhanced spiral CT was performed in 27 cases of pancreatic adenocarcinoma. After plain CT examination, performed arterial phase（25s after infusion）and portal venous phase（60～70s after infusion）with a 150ml bolus injection of contrast material at 3ml/s. CT attenuation values of tumor and normal pancreas in all scanning phase were obtained and the tumor-pancreas contrast was calculated. Results Mean tumor enhancement were 48±8 HU（arterial phase）and 72±6 HU（portal venous phase）, normal pancreas enhancement were 125±18 HU、98±11 HU, mean tumor-pancreas contrast was significantly differenced on arterial phase （73±21 HU）and portal venous phase （25±12 HU）. Conclusion Excellent tumor-pancreas contrast is obtained with arterial phase scans, as such it is of significance reference value for diagnosis pancreatic adenocarcinoma.
