ABSTRACT
Objective To explore the feasibility of quantitative assessment of pancreatic perfusion using dynamic contrastenhanced MRI (DCE-MRI).Methods Totally 68 healthy volunteers were divided into youth,middle and old groups according to ages.All volunteers underwent pancreas DCE-MRI examination.Images were transmitted to Research-DCE MRI Tool workstation to calculate the quantitative parameters,including volume transfer constant (Ktrans),interstitium-toplasma rate constant (Kep),interstitial volume (Ve) and plasma volume (Vp).Independent sample t test and one-way ANOVA test were used to evaluate the differences of pancreatic perfusion.Results There were no significant differences of Ktrans,Kep, Ve and Vp between male and female;Ve in old group was higher than that in youth and middle groups (P =0.036,0.001);Vp of pancreatic head was higher than that of pancreatic body and tail (P=0.011,0.023).Conclusion DCE-MRI can be applied to provide a reliable quantitative assessment of pancreatic perfusion noninvasively.The parameters of DCE-MRI of pancreatic perfusion are independent of gender but vary with age and pancreatic sites.
