    Purpose : To compare the images of arterial phase (AP) and portal venous phase (PVP) in the evaluation ofconspicuousness of lesion and peripancreatic arterial and venous opacification in pancreatic diseases. Materialsand Methods : Dual-phase spiral CT was performed in 37 patients with pancreatic adenocarcinoma and 21 patientswith pancreatitis. CT scans were performed with 5mm collimation at 1 : 1 pitch table feed. Images of AP and PVPwere obtained at 30 and 65 seconds after administration of contrast material, was initiated. Using a gradingsystem, images were analalysed for conspicuousness of lesion and vascular opacification(grade 1=good, grade2=fair, grade 3=poor). Results : In pancreatic adenocarcinoma, 35 and 36 of 37 cases showed low attenuation on APand PVP, respectively. With regard to conspicuousness of tumour, PVP(mean grade : 1.24) was superior AP(mean grade: 1.43), but not significantly(p=0.0745). In arterial opacification, AP(mean grade : 1.03) was significantlysuperior to PVP(mean grade : 1.30, ; p=0.0051). In venous opacification, PVP(mean grade : 1.19) was significautlyto AP(mean grade : 2.41 ; p
