摘　　要：目的:利用MSCT灌注成像技术,探讨正常胰腺64排螺旋CT灌注参数特征。方法:对非胰腺疾病60例患者行胰腺64排MSCT灌注扫描及常规双期增强扫描,计算出BF,PEI,TTP,BV感兴趣区的灌注参数,分析正常胰腺的灌注参数及特点。结果:正常胰腺的BF值随着年龄的增大呈明显下降趋势,且灌注参数BF值与年龄呈负相关。TTP值随着年龄的增加呈上升趋势,不同年龄组之间PEI、BV值的差异无统计学意义(P>0.05);不同年龄段正常胰腺胰头部和胰体尾部BF、PEI、TTP、BV值差异无统计学意义(P>0.05)。结论:胰腺64排螺旋CT灌注成像方法简单可行,能反映胰腺组织的血流动力学变化。Objective： Using multi-slice CT （MSCT）perfusion techology to evaluate the feature of 64-Slice CT perfusion imaging （CTPI）in normal pancreas. Methods：64-Slice CT perfusion imaging was performed on 60 patients without pancreatic disease. The perfusion parameters were calculated and analyzed, including Perfusion parameters blood flow （BF）, blood volume（BV）, peak enhancement imaging（PEI）, and time to peak（TYP）. Results：The perfusion parameter BF of the normal pancreas reduced with age while TIP increased with age. MrIT and BV had no obvious trend with age; There was no difference between the pancreatic head and body-tail. Conclusion：64-Slice CT perfusion imaging of the pancreas continues to be a feasible and effective method of reflecting the hemodynamic changes of pancreatic tissue.
