Will Inversion Recovery with On-Resonant Water Suppression Be Another Way to Routinely Exploit Off-Resonance Effects with MR Imaging?

摘要

In this issue of Radiology, Korosoglou et al (1) evaluated the utility of inversion recovery with on-resonant water suppression (IRON) in combination with injection of the long-circulating monocrystalline iron oxide nanoparticle-47 for contrast material–enhanced magnetic resonance (MR) angiography. They found that IRON MR angiography in conjunction with superparamagnetic nanoparticle administration provided high intravascular contrast over a long time and without the need for image subtraction.
