肝脏的CT灌注成像及其研究进展

CT Perfusion Imaging of the Liver and Its Study Headway

随着影像学技术的发展,有关功能成像的研究日益增多。CT灌注成像(CT perfusion,CTP)作为主要功能成像的一种,能准确、相对简洁的定量评估器官、组织血流灌注状态,因此具有广阔的临床应用前景。就肝脏CT灌注成像的基本原理、扫描技术、临床应用、优势和不足等方面进行综述。

With the development of radiological technology,the studies up on function imaging increases day by day.As one of the primary function imaging,CT perfusion imaging can provide a precise and relative simple method to quantitatively estimate blood perfusion status in organs and tissue,so it will have broad prospect for clinical application.The principle techniques and the clinical application of the CT perfusion,and its advantage and shortage are reviewed.
