SPECT全(quan)稱是(shi)單光子發射(she)型(xing)計算機斷層(ceng)掃描, 它是(shi)以(yi)注(zhu)入人體(ti)放(fang)射(she)性核素為放(fang)射(she)源, 運(yun)用電子計算機對(dui)信息進行處理, 并重建(jian)機體(ti)相應部分斷層(ceng)影(ying)像(xiang)(xiang)(xiang)(xiang)的(de)數學和物理技術(shu), 其特點(dian)是(shi)成(cheng)像(xiang)(xiang)(xiang)(xiang)速度快(kuai), 可(ke)平面顯(xian)(xian)(xian)像(xiang)(xiang)(xiang)(xiang)、斷層(ceng)顯(xian)(xian)(xian)像(xiang)(xiang)(xiang)(xiang), 亦可(ke)連續動(dong)態顯(xian)(xian)(xian)像(xiang)(xiang)(xiang)(xiang), 因(yin)此它不僅具有CT的(de)形(xing)態診(zhen)斷, 而(er)且可(ke)以(yi)觀察臟器功能的(de)動(dong)態變化, 具有較高的(de)診(zhen)斷價值。廣泛應用于(yu)甲狀(zhuang)腺顯(xian)(xian)(xian)像(xiang)(xiang)(xiang)(xiang)、局部腦血(xue)(xue)流顯(xian)(xian)(xian)像(xiang)(xiang)(xiang)(xiang)、心(xin)(xin)肌灌(guan)注(zhu)顯(xian)(xian)(xian)像(xiang)(xiang)(xiang)(xiang)、門電路心(xin)(xin)血(xue)(xue)池顯(xian)(xian)(xian)像(xiang)(xiang)(xiang)(xiang)、骨骼顯(xian)(xian)(xian)像(xiang)(xiang)(xiang)(xiang)(全(quan)身、局部)  、肝(gan)(gan)顯(xian)(xian)(xian)像(xiang)(xiang)(xiang)(xiang)、肝(gan)(gan)動(dong)脈(mo)灌(guan)注(zhu)顯(xian)(xian)(xian)像(xiang)(xiang)(xiang)(xiang)和血(xue)(xue)池顯(xian)(xian)(xian)像(xiang)(xiang)(xiang)(xiang) 、腎血(xue)(xue)流及腎動(dong)態顯(xian)(xian)(xian)像(xiang)(xiang)(xiang)(xiang)、腸道出血(xue)(xue)顯(xian)(xian)(xian)像(xiang)(xiang)(xiang)(xiang)、肝(gan)(gan)膽顯(xian)(xian)(xian)像(xiang)(xiang)(xiang)(xiang)、肺灌(guan)注(zhu)顯(xian)(xian)(xian)像(xiang)(xiang)(xiang)(xiang),并可(ke)根據臨(lin)床需要(yao)開展(zhan)各(ge)種特殊檢查(cha)。
