The microstructure and physiology of the pancreas is complex. Water diffusion may reveal this complexity. We have, therefore, focused on developing diffusion tensor imaging (DTI) protocols and processing means with the aim of detecting changes in the tensor parameters upon malignant growth. Results based on studies of 18 healthy volunteers reveal that the diffusion in the pancreas is highly anisotropic and the tensor diffusion coefficients vary significantly between healthy subjects and within different parts of the pancreas. We predict that changes in the pancreatic microstructure caused by pancreatic ductal adenocarcinoma can be detected by DTI.
