补充资料:放射性核素静态显(成)像
放射性核素静态显(成)像
放射性核素显(成)像方法之一。显(成)像剂在脏器内或病变处的浓度处于稳定状态时进行的显(成)像。这种显(成)像允许采集足够的放射性计数用以成像,故所得影像清晰,在临床上多用于观察脏器和病变的位置、形态、大小和放射性核素分布情况。根据脏器整体和局部放射性的高低可对脏器的整体功能和局部功能作出判断。根据一定的生理数学模型,从各个局部的放射性核素浓度还可计算出一些定量参数,如局部脑血流量、局部葡萄糖代谢率等。将局部参数值的大小用不同的灰度或颜色成像,称为参数成像(parametric imaging),或称功能性成像(functional imaging),是定量研究脏器局部功能和局部代谢的较好方法。静态显(成)像所用的显(成)像剂较少,显(成)像时间较长,故可用扫描机、γ照相机或ECT显(成)像。
