Abstract:
Objective To assess the value of multisection spiral CT perfusion in evaluating severity of acute pancreatitis (AP). Methods Eighty two AP patients, who were admitted to the hospital between August 2006 and January 2008, were enrolled. Multisection dynamic CT (MSCT) perfusion was performed on all patients 48-72 hrs after admission by using a multisection CT scanner (Siemens somatom sensation 64), and 30 healthy subjects were served as controls. The data were processed on a siemens workstation using PCT software package. The parameters including blood folw (BF), blood volume (BV), peak time (TTP) and surface permeability (PS) were measured and compared. Results The values of BF, BV, TTP and PS in AP patients were (110.57±60.04) ml·100 ml-1·min-1, (156.68±65.11) ml/L, (146.58±29.46) 0.1 s, (110.73±62.66) 0.5 ml·100 ml-1·min-1, respectively. The decreased BF and BV were found in AP patients compared with controls (P<0.05). However, there was no significant difference in TTP and PS between two groups (P>0.05). Conclusions The decreased perfusion in AP patients was associated with the severity of the disease. The parameters of BF and BV can be used to predicte the severity of AP.
