Abstract Objective: To study the correlation of blood perfusion values with CT severe index(CTSI) and clinical severity of acute pancreatitis(AP). Methods: Seventy-nine patients and in which 63 cases had AP and 16 normal cases as control were enrolled in this study and all of them had undergone MSCT perfusion imaging. The mean values of blood flow(BF), blood volume(BV), mean transit time(MTT) and permeability surface(PS) were measured on ADW 4.2 workstation with perfusion 3 software package. Using statistical software was to emphatically analyze the difference between the AP and control group and the correlation of perfusion values with CTSI and APACHEⅡ respectively. Results: There was a significant difference between the AP and control group and a negative correlation of MSCT perfusion values of BF and BV with the CTSI and APACHEⅡ scores(r=-0.865, r=-0.703; r=-0.817, r=-0.703; P<0.01), but MTT and PS values did not have correlation with CTSI and APACHEⅡ scores(r=-0.185, r=0.094; r=-0.192, r=0.141; P>0.05). Conclusion: BF and BV are markedly decreased in AP. BF and BV have a significant correlation with the CTSI and clinical severity of AP and can be the reliable indexes in assessing the severity of AP.
