目的 评价螺旋CT双期扫描对急性胰腺炎的诊断价值。方法 回顾性分析 6 4例经临床证实的急性胰腺炎CT平扫和增强扫描资料。结果 6 4例中 ,急性水肿型胰腺炎 40例 ,CT表现为胰腺肿大 ,胰周脂肪层模糊或消失 ,肾前筋膜增厚 ,部分见少量胸水。急性出血坏死型胰腺炎 2 4例 ,其中坏死型 2 1例 ,化脓型 2例 ,出血型 1例 ,CT表现为胰腺内点状、片状或大范围无增强效应的低密度坏死灶 ,胰周间隙渗出及积液 ,蜂窝织炎 ,胰内或外出现气体或高密度出血灶。结论 螺旋CT双期扫描对急性胰腺炎的分型 ,临床治疗方案的选择 ,以及判断预后有重要诊断价值。

Objective To evaluate the diagnostic value of spiral CT dual-phase scan on acute pancreatitis. Methods CT plain scan and enhanced scan data of 64 cases acute pancreatitis proved by clinic were analyzed. Results There were 40 cases diagnosed acute edema pancreatitis, CT findings included swelling of pancreas, blurring or disappearing of peripancreatic fat, thicken of kidney fascial planes and hydrothroax. And there were 24 cases diagnosed acute hemorrhagic necrosis pancreatitis,consisted of necrosis type 21 cases, maturation type 2 cases and hemorrhagic type 1 case. CT showed dot, patch and large extent non-enhancement iso-density necrosis, peripancreatic space effusion and fluid collection, phlegmon, gas or hyper-density hemorrhage inside or outside pancreas. Conclusion Spiral CT dual-phase scan has an important diagnostic value in classifying acute pancreatitis, choosing therapy and assessing prognosis.[
