急性胰腺炎的影像表现与淀粉酶改变的对比分析

目的：探讨急性胰腺是的CT、B超表现与血清、尿淀粉酶变化的相关性以指导临床治疗。方法：回顾性分析已确诊的急性胰腺炎63例．将其CT改变分为5个级别．分别与B超表现及相应的血清、尿淀粉酶数值对比。结果：CT改变为A级时血尿淀粉酶轻中度升高．B级时中度升高．C级时显著升高．D级时趋向下降．E级时显著下降。结论：CT检查可以准确地反映急性胰腺炎A、B、C、D、E级的病理变化；CT诊断优于B超、B超对胆源性胰腺炎的诊断有明确帮助，明显优于淀粉酶值的改变。对于早期仅限于间质水肿的炎症．CT、B超诊断困难．主要依靠临床症状、体征，血、尿淀粉酶的变化来做出诊断。

Correlation of CT and Ultrasonography Findings of Acute Pancreatitis with Changing of Serum and Urine Amylase

Objective:To evaluate the relationship between CT,ultrasonography findings and the changing of serum and urineamylase in diagnosis of acute pancreatitis.Methods:63 cases with acute pancreatitis were divided into fivegrades based on CT findings,and the CT grading relevant to the serum and urine amylase were analyzed.Results:The serum and urine amylase increase slightly or moderately in grading A,moderately in grade B,markedly in grade C,but tended to decrease in grade D,and decreased dramatically in grade E.Conclusion:CT examination is superior to the serum and urine amylase in evaluation of acute pancreatitis with B,C,D andE.CT is superior to ultrasonogphy in demonstrating the extent,size,fluld collecting of lesions in acute pancrearitis.But for grade A,accurate diagnosis should be made based on CT findings combined with the changing of serum and urineamylase.
