Abstract

Abstract: To investigate the magnetic resonance imaging (MRI) characteristic of acute edematous pancreatitis (AEP) in canines, ten local adult canines were used to establish AEP models by sodium taurocholate and trypsin retrograde perfusion. MRI was performed before and after perfusion. FSE-T2WI-TRIG and FSE-T2WI-FS-TRIG images preferred best for subjective and objective analysis through MRI multi-sequence scanning and contrast enhanced scans can be performed if necessary. Pancreas was found diffuse enlargement with an irregular shape. Pancreatic parenchyma was also found hyperintense uneven signal and high signal was found compared with the same liver layer in T2WI. With extracellular fluid surrounding and irregular pancreatic margins, hyperintense stripe signal was also found in T2WI. The Gad-enhanced images showed inhomogeneous enhancement in pancreas parenchyma of AEP canines, and the average enhancement peak time was 60-90 s after injection of Gad medium delayed enhancement was found. Our research integrated these selected sequences can be used for clinical examination of AEP canines. MRI characteristic of AEP canines provided important reference for the diagnosis of AEP canines.

Key words: acute edematous pancreatitis in canines, magnetic resonance imaging, multi-sequence scanning, enhancement scan
