From: Differential diagnosis of thickened myocardium: an illustrative MRI review
A 75-year-old man with cardiac amyloidosis. a Sequential inversion recovery T1-weighted gradient echo images with a variable inversion time trying to null normal myocardium show the difficult to determine the optimal inversion time to null myocardium. The blood pool and the myocardial nulling occurs earlier at 225 ms than the splenic nulling (275 ms). b Short-axis T1-weighted inversion recovery gradient echo images obtained at (b) 4 minutes and (c) 8 minutes after the injection of contrast agent. The myocardium displays predominantly subendocardial LGE at 4 minutes, but it is diffusely enhanced at 8 minutes
