¹⁹F signals co-register with the infarct area. A ¹H images with T2 mapping for identification of edema (blue lines) and late gadolinium enhancement (LGE) for infarct size (gray lines) were recorded (left) and fused with ¹⁹F images representing patchy macrophage presence (red lines). The ¹⁹F image overlay with the ¹H image was performed automatically encoded with the “hot iron-lookup table” (HILT) in arbitrary units (right). Red arrows = signals in the sternum and ribs. Quantitative analysis of individual whole heart ¹⁹F volumes (HILT) and B edema extent (blue) as well as C infarct size (gray). D The ¹⁹F signal-to-noise ratio (SNR) of infarcted segments was significantly correlated with local T2 and T1 times.
