Angiographie par résonance magnétique avec injection de produit de contraste : évolution vers le corps entier et le temps réel

Contrast enhanced MR angiography : evolving towards whole-body real time acquisitions MRA includes all techniques used to depict vessels with MR. Gadolinium contrast injection combined with gradient echo sequences is the technique of choice for vascular imaging. Technical advances now allow faster acquisitions. The purpose of this article is to present two main advances with MRA: whole-body MRA and dynamic 3D MRA. Technical considerations, acquisition techniques, advantages and pitfalls based on our experience with a 1.5T MR unit will be discussed in order to promote their use in routine clinical practice.
