Clinical and image study of pancreatic hemocirculatory change in patients with acute pacreatitis / 中华消化杂志

ABSTRACT

Objective To study the change of pancreatic hemocirculation in patients with acute pancreatitis by magnetic resonance perfusion (MRP) and to explore its relationship with pancreatic severity. Methods With a prospective investigation method, APACHEⅡscores, systemic inflammatory response syndrome (SIRS) scores, Binder scores and C-reactive protein (CRP) values were recorded within 72 h in patients with severe acute pancreatitis (SAP,n=15) and mild acute pancreatitis (MAP,n=17), while other 19 volunteers were as controls. MRP were performed on 32 patients and 19 controls. Patients in SAP group were evaluated by above criteria after two-weeks treatment and MRP were performed in 12 of them. All cases with bolus injection of Gd-DTPA (0.2 mol/kg) were scanned by transversal same slice and fast spoil phase gradient echo. Three groups datum of MIR and MSR were gained by ROI time-signal graphy of pancreatic head, body and trail which were calculated by Perfxproject software. Results ① The rates of MIR and MSR in SAP group were lower than MAP group (P0.05).Conclusion MRP is an objective imaging technique, which can reflect the hemocirculatory variety in acute pancrea-titis.It may have a considerable value in evaluating the severity of acute pancratitis.
