Three typical same ROIs placement of pancreatic body of healthy group on signal intensity image (a), ADC map (b) and FA map (C).

Three typical same ROIs placement within the highest SI area in pancreas in AP group on signal intensity image (a), ADC map (b) and FA map (C).
Fig 3.
A 40-year-old woman with mild AP.
Fat suppression Lava-flex T1 (a) and FRFSE T2 (b) weighted images show the swollen pancreatic tissue, the thickened fascia of pancreas (arrows) and edematous peripancreatic fat (arrowhead). DTI(c) shows the increased signal in pancreatic parenchyma, particularly pancreatic head (arrowhead) and fuzzy peripancreatic fat (arrow).
Fig 4.
A 43-year-old woman with moderate AP and cholecystolithiasis.
Fat suppression Lava-flex T1 (a) and FRFSE T2 (b) weighted images show the swollen pancreatic tissue, and edematous peripancreatic fat (arrowhead). DTI(c) shows the swollen pancreatic parenchyma.
Fig 5.
A 76-year-old woman with severe necrosis AP.
Lava-flex T1 (a), FRFSE T2 (b), contrast Lava-flex T1(c), DTI(d), ADC map (e) and FA map (f) weighted images show a well-marginated necrosis area without enhancement located in the whole pancreatic tissue(arrow) and a pseudocyst in omental sac.

Comparison of the FA and ADC value between edematous and necrotic AP.
Table 4.
Correlation of the pancreas ADC and FA value with AP severity determined by the MRSI.
Fig 6.
The pancreatic mean ADC value (a) and FA value (b) contrast between in the AP group and normal group, we can gain that the pancreatic ADC value and FA value in the AP group was significantly lower than in the normal group.
