CT灌注成像是利用动态增强CT和图象后处理技术来反映组织血流灌注状态的功能成像方法,可提供组织器官血流动力学信息,这为研究脑出血血肿周围组织的血流动力学变化提供新的方法。本文就CT灌注成像技术的特点及基于此技术对脑出血血肿周围低血流灌注的相关研究进行综述。
CT perfusion imaging is a functional imaging method that uses dynamic contrast-enhanced computed tomography (CT) and post-processing techniques to reflect tissue perfusion, providing hemodynamic information on tissues and organs. This study was conducted to investigate the hemodynamic changes in the tissues surrounding the intracerebral hematoma Provide new methods. In this paper, the characteristics of CT perfusion imaging and the related research on the hypoperfusion perfusion around intracerebral hemorrhage based on this technique are reviewed.
