近年来强势推出的多层螺旋CT(multi-detector CT,MDCT或multi-slice CT,MSCT)的特点是扫描为密集取数,具有扫描速度快、成像时间短等特点;快速扫描方式及强大的后处理软件应用,使得CT技术不再是单纯的形态学表达,而是进入功能成像(functional imaging)的新时代。CT灌注成像(perfusion imaging)是以核医学放射性示
In recent years, the strong multi-slice CT (multi-detector CT, MDCT or multi-slice CT, MSCT) is characterized by intensive scanning, fast scanning speed and short imaging time. The rapid scanning method and powerful Post-processing software applications make CT technology no longer a simple morphological expression, but a new era of functional imaging. CT perfusion imaging (perfusion imaging) is a radioactive nuclear medicine show
