[Abstract] Objective: To investigate the correlation between the severity of acute pancreatitis (AP) on MR imaging and liver function.Materials and Methods: There were 64 patients with AP, all of whom had performed abdominal MR imaging. AP was categorized into types of edematous and necrotizing, and graded into mild (0-3 scores), moderate (4-6 scores) and severe (7-10 scores) according to the MR severity index (MRSI). The results of liver function test (ALT and AST) was noted and compared with the severity of AP on MRSI.Results: In the 64 patients with AP, 56 patients were edematous and 8 patients were necrotizing on MR imaging. The frequencies of ALT and AST elevated were both 100% in necrotizing AP, which were significantly larger than 55.4% (ALT) and 60.7% (AST) in edematous AP (P=0.014 and P=0.027, respectively). The frequencies of ALT and AST elevated were 48.8% and 53.5% in mild AP, 73.7% and 78.9% in moderate AP, and both 100% in severe AP, respectively. The frequency increasing of liver function abnormality tended to follow MRSI scores increasing. However, no significant difference for the frequencies can be seen among mild, moderate and severe AP.Conclusion: The necroses of AP on MR imaging may help to predict liver function abnormality in AP. However, MRSI could not be as index for predicting the abnormality of liver function in AP.
