作者首次报道了使用无创的动态CT对人胰腺血液灌流量测定的方法。此方法不但可以了解胰腺的解剖形态,还可以了解其功能状态。用西门子CT装置(Somatom Plus),于静脉快速注入50ml碘必乐后,分别于注射后0、7、10、13、16、21、26、31、37.5和44s对胰腺进行单一部位扫描,扫描时间1s,层厚10mm。然后通过以下公式计算时间-密度值得出灌 For the first time, the authors report a method for the determination of blood perfusion of human pancreas using non-invasive dynamic CT. This method can not only understand the anatomy of the pancreas, but also understand its functional status. A single site scan of the pancreas was performed at 0, 7, 10, 13, 16, 21, 26, 31, 37.5, and 44 s after injection with Somatom Plus, Time 1s, layer thickness 10mm. Then calculate the time-density value by the following formula
