Second color, or hot spot, fluorine imaging benefits from 3D acquisition from both a signal localization point of view and a desire to maximize signal sensitivity. Here we show fluorine nanoparticle-labeled macrophage infiltration into infarcted myocardium using a gated 3D turbo spin echo sequence, and improve the SNR and sensitivity using a regularized reconstruction technique which utilizes side information obtained from proton scout images.
