All of the above sequences rely on the selection of an optimal inversion time.
In a normal person, the null point of blood typically occurs earlier than myocardium (Figure 1), but in amyloidosis, due to diffuse infiltration and Gad uptake, the myocardium appears the darkest at an inversion time earlier than that of the blood pool (Figure 13).
The inversion time is shorter than normal and lengthens in large incremental steps.
