It is difficult to differentiate the solid pseudopapillary tumor of the pancreas (SPTP) from pancreatic neuroendocrine tumor (PNET). Enhanced T2* weighted angiography (ESWAN) technique can simultaneously obtain amplitude, phase, R2* and T2* values, which can quantitatively assess the magnetic sensitivity characteristics of tissues. DTI can evaluate the diffusion of water molecules in living tissues. This study founded that R2* and T2* of ESWAN, fractional aniso (FA) and volume ratio aniso (VRA) of DTI were significantly different (P<0.05) and the AUC was 0.860(sensitivity: 100%; specificity: 79.2%). Therefore, ESWAN combined with DTI may be an effective method to identify SPTP and PNET.
