a 4-chamber SSFP image in a patient with cardiac amyloidosis shows concentric LV thickening (straight arrow). There is also thickening of the interatrial septum (curved arrow). b Post contrast T1-w inversion recovery gradient echo image shows diffuse sub-endocardial to mid myocardial LGE of the ventricles (straight arrow), interatrial septum (curved arrow) and the atrial walls (arrowhead). c Short-axis TI scout (Look Locker sequence image) at the level of mid-ventricular septum in a patient with cardiac amyloidosis. At an inversion time of 150 milliseconds, both the blood pool (LV) and myocardium (M) are dark. This is due to diffuse myocardial infiltration with amyloid, which takes up gadolinium and results in T1 shortening
