双能CT虚拟单能技术在CT血管成像中的应用进展
Application advances of dual energy CT virtual monoenergetic imaging in CT angiography
摘要
Abstract
Dual energy CT(DECT)produces multiple energy spectrum image sets by using X-ray with two different energy levels.Compared to conventional CT,DECT virtual monoenergetic images(VMI)can enhance contrast between vessels and surrounding structures,improve lesion detection,reduce artifacts,and minimize radiation exposure in CT angiography(CTA).The VMI technique improves the quality of CTA,thereby reducing the failure rate of the examination.Furthermore,the VMI technique allows for better evaluation of plaque components,thrombi,vascular details,and small vessel branches.The advantages of VMI are highly significant for procedures involving blood vessels,including surgical and interventional therapies for vascular diseases.This article reviews the research progress and clinical applications of VMI in vascular imaging.关键词
