摘　　要：目的:探讨螺旋CT增强扫描对急性胰腺炎的诊断及病情评估的应用价值。方法:选择42例急性急性胰腺患者,进行CT平扫及增强扫描,对比平扫及增强扫描典型影像学变化的比率以及CT分级差异。结果:胰腺周围渗出、肾前筋膜增厚、胆总管扩张、胰腺边缘模糊、胰腺内点片状坏死增强CT检出率高于平扫CT,增强CT扫描胰腺病变评级高于平扫CT,差异具有统计学意义。结论:增强CT扫描能够准确显示急性胰腺炎病变特点,为胰腺炎的诊断及病情评估提供依据。Objective： To investigate the appling vaule of enhancement scanning with helical CT for dignosis and evaluation on acute pancreatitis. Methods： Forty two cases of patients with acute pancreatitis were detected with conventional scanning and enhancement scanning with helical CT, incidence rate of typal signs and grade of CT were contracted. Results： Detecting rate of exudation surrounding pancreatitis, thickening of prerenal fascia, choledochectasia, edge unsharpness of pancreatitis and lamellar necrosis of pancreatitis were higher in enhancement scanning than in conventional scanning. Grade of pathological changes were higher in enhancement scanning than in conventional scanning, the difference was singificant. Conclusion： Enhancement scanning with helical CT could punctually display affection characteristic of acute pancreatitis, and improve reference for diagnosis and evaluation of acute pancreatitis.
