Perfusion imaging of human acute pancreatitis using dynamic computed tomography

Objective:To describe CT perfusion imaging in patients with acute pancreatitis.Methods:CT perfusion imaging was performed in 60 patients including 30 healthy subjects without pancreatic diseases.The raw data was calculated by Siemens perfusion CT(PCT) and the perfusion values were compared.Results:Blood flow in patients with pancreatitis was(0.95±0.19)ml/(min·ml),in control was(1.63±0.34)ml/(min·ml).Blood volume in patients with pancreatitis was(0.22±0.06)ml/ml,in control was(0.26±0.04)ml/ml.Permeability in patients with pancreatitis was(1.25±0.97)ml/(min·ml),in control was(0.14±0.07)ml/(min·ml)(P0.05).There was no significance between contrast CT and PCT.Conclusion:Perfusion was reduced and permeability was improved in patients with pancreatitis.The information afforded by CT perfusion imaging can help diagnosis of pancreatitis in the early stage.
