1 Chi n J Interv I maging Ther,2005, Vol 2,No Multi-slice CT diagnosis of pul monary embolism MA Da- qi ng * ( Depart ment of Radiology, Beijing Friendshi p Hospital Af filiated of Capital University of Medical Sciences, Beij ing , China) ABSTRACT Multi- slice CT ( MSCT) has beco me the first modality for i maging diagnosis of pul monary embolis m( PE) instead of nuclear medici ne and transcat heter pul monary angi ography. Diagnosti c fi ndi ngs of CT pul monary angi ographi y is based on the presence of partial or co mplete filling detects within the contrast filled lumen of pul monary arteries. This article descri bed the techni ques and diagnostic val ue of MSCT pul monary angi ographi y f or PE. Advantages of MSCT for PE i maging were discussed.
