摘要

非对比增强MR血管成像(NCE-MRA)具有无辐射、无需注射对比剂等优势,已广泛用于临床.利用超高场MR设备可有效提高NCE-MRA图像质量,但受限于线圈,7.0T设备目前仅用于检查脑血管.5.0T MR系统的问世使全身超高场NCE-MRA成为可能.本文初步探索5.0T全身NCE-MRA用于人体的价值.

Abstract

Non-contrast enhanced MR angiography(NCE-MRA)has been widely used in clinic since advantages of non-radiation and non-contrast media.The image quality of NCE-MRA could be effectively improved using ultra-high field MR scanner,yet 7.0T devices were limited by coils and usually used for cerebrovascular scanning.The invention of 5.0T ultra-high field MR system brings new opportunities for whole body NCE-MRA.The preliminary application of 5.0T whole body NCE-MRA in human body were explored in this article.
