Importance of b value in diffusion weighted imaging for the diagnosis of pancreatic cancer.

Aim: To investigate the use of multi-b-value diffusion-weighted imaging in diagnosing pancreatic cancer.

Methods: We retrospectively analyzed 33 cases of pancreatic cancer and 12 cases of benign pancreatic tumors at the Second Affiliated Hospital of Kunming Medical University from December 2008 to January 2011. The demographic characteristics, clinical presentation, routine magnetic resonance imaging and diffusion weighted imaging (DWI) features with different b values were reviewed.
