Correlation of CT Findings of Acute Pancreatitis with Changing of Serum and Urine Amykase

<b<Objective:</b< To evaluate the relationship between CT findings and the changing of serum and urine amylase in diagnosis of acute pancreatitis. <b<Methods:</b< 63 cases with acute pancreatitis were divided into five grades based on CT findings,and the CT grading relevant to the serum and urine amylase were analyzed. <b<Results:</b< 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. <b<Conclusion:</b< CT examination is superior to the serum and urine amylase in evaluation of acute pancreatitis with B, C, D and E. But for grade A, accurate diagnosis should be made based on CT findings combined with the changing of serum and urine amylase.
