Abstract：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)(P＜0.05). 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.
