Abstract Objective: To evaluate the influence of different prandial state on pancreatic stiffness by MR elastography in healthy volunteers. Methods: Pancreatic stiffness measurements were got and compared in 24 healthy volunteers at 40 Hz and 60 Hz before and after a standard liquid meal(an effective method to increase pancreatic blood flow). Results: At 40 Hz, the mean pancreatic stiffness measurements before meal was significantly higher than after meal (1.174±0.121) kPa vs (1.106±0.123) kPa, t=5.95, P<0.001. At 60 Hz, the mean pancreatic stiffness measurements before and after a standard meal had no significant difference ((2.221±0.223) kPa vs (2.266±0.251) kPa, t=0.57, P=0.57). There was 6.2% difference between the two prandial states at 40 Hz. The image quality score of wave was (4.25±0.73) at 40 Hz and (2.41±0.83) at 60 Hz(P<0.001) at fast state. Conclusion: Compared with 60 Hz, 40 Hz had better wave pattern and can detect tiny changes of pancreatic stiffness,which is more suitable for pancreatic MRE.
