【摘要】　目的　利用首過時間技術進行全胰腺CT灌注掃描，了解正常胰腺CT灌注的特點。　方法　 2006年6月-2007年3月， 64例正常胰腺患者行64排螺旋CT灌注掃描，測量胰頭、胰體及胰尾的灌注值、強化峰值、達峰時間和血容量。分別按患者的性別、年齡及胰腺測量的部位分組，將灌注參數進行統計分析。　結果　 ①男性胰腺的血容量高于女性（P lt;0.05），其余灌注參數在兩性間差異無統計學意義（P gt;0.05）。②41~60歲組的灌注值低于 lt;40歲組和 gt;60歲組； gt;60歲組的強化峰值高于41~60歲組；41~60歲組的達峰時間長于 lt;40歲組； gt;60歲組的血容量高于41~60歲組（P lt;0.05）。③胰體和胰尾的灌注值高于胰頭（P lt;0.05），其余灌注參數在胰腺不同部位差異無統計學意義。　結論　正常胰腺血流狀況在不同性別、不同年齡段及不同部位存在差異，首過時間技術應用于正常胰腺能反映這些特征。
【Abstract】　Objective　 To investigate the CT perfusion features of normal pancreas with first-pass technique with 64-MDCT.　Methods　 Perfusion CT was performed on 64 patients with normal pancreas from June 2006 to March 2007. Four perfusion parameters, including perfusion, peak enhancement, time to peak, and blood volume, were obtained at the head, body and tail of the pancreas. Perfusion parameters were compared between different sexes, among different age groups and among different sites.　Results　 ① Blood volume of male was significantly higher than that of female (P lt;0.05). ② The perfusion value in the age group of 41-60 was significantly lower than that in the age group of lt;40 and gt;60 (P lt;0.05). The peak enhancement in the age group of gt;60 was significantly higher than that in the age group of 41-60 (P lt;0.05). The time to peak in the age group of 41-60 was significantly longer than that in the age group of lt;40 (P lt;0.05). The blood volume in the age group of gt;60 was significantly higher than that in the age group of 41-60 (P lt;0.05). ③The perfusion values of the body and the tail were significantly higher than that of the head (P lt;0.05).　Conclusion　 There are significant differences in the perfusion parameters between different sexes and among several age groups and sites. The first-pass technique of perfusion applied in normal pancreas can reflect these features.
