We hypothesized that DWI could be useful to depict the pancreatic cancer, which was not identified by conventional image technique such as T1-WI or T2-WI. Ten subjects with pancreatic cancer were included in this study. We compared the image contrast between tumor and normal pancreatic parenchyma divided by the muscle (C/M ratio) in each image sequence. The mean C/M ratio of the DWI was significantly greater than those of the T2-WI and T1-WI. The mean C/M ratio between T2-WI and T1-WI was not statistically significant. These results support the hypothesis that DWI may be useful to depict the pancreatic cancer.
