摘要

目的：探讨急性胰腺炎CT灌注成像特征。方法：采用40层螺旋CT对60例患者进行胰腺CT灌注检查，其中包括30例正常对照者和30例急性胰腺炎病例。灌注成像原始数据经Siemens体部灌注软件测量，并对急性胰腺炎和正常胰腺的灌注参数进行比较。结果：急性胰腺炎组的血流量为（0.95±0.19）ml/（min·ml），低于正常组的（1.63±0.34）ml/（min·ml），血容量为（0.22±0.06）ml/ml，低于正常组的（0.26±0.04）ml/ml，通透性为（1.25±0.97）ml/（min·ml），高于正常组的（0.14±0.07）ml/（min·ml），差异有显著性（P＜0.05）。常规CT增强与CT灌注成像检出率差异不显著。急性水肿型胰腺炎和急性出血坏死型胰腺炎灌注参数差异不显著。结论：急性胰腺炎血流灌注减低，通透性升高。CT灌注成像有利于早期辅助诊断急性胰腺炎。

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.
