  Background: Previous studies showed that the dilated main pancreatic duct (MPD) and pancreatic cysts were the important predictors of the subsequent development of pancreatic cancer. The purpose of this study was to reveal the utility of non-contrast reduced radiation dose CT with iterative reconstruction for screening in high risk pancreatic cancer individuals by assessing the dilated MPD and cysts by using abdominal phantoms. Materials and methods: Two phantoms with normal and abnormal pancreas with dilated MPD (5 mm) and cysts (5 mm, 10 mm and 15 mm) were constructed. Each phantom was scanned by ten images using following three protocols: 120 kVp and 120mA with filtered back projection (FBP) algorithm (120 kVp-FBP), 80 kVp and 168mA with FBP algorithm (80 kVp-FBP), and 80 kVp and 168mA with sinogram affirmed iterative reconstruction (SAFIRE..
