CT扫描能准确地显示脑部肿瘤的影像学表现,但对脑部肿瘤在生理功能方面的变化仍缺乏特异性。CT灌注成像(CT perfusion imaging)是利用动态增强CT和图像后处理技术来反映组织血管化程度和血流灌注状况,提供组织器官血流动力学方面信息的功能性成像方法,可分析脑肿瘤的生理功能变
CT scan can accurately show the imaging features of brain tumors, but there are still no specific changes in the physiological functions of brain tumors. CT perfusion imaging is a functional imaging method that uses the dynamic contrast-enhanced CT and post-processing techniques to reflect the degree of vascularity and perfusion of tissue to provide information on the hemodynamics of tissues and organs. CT perfusion imaging Physiological functions change
