Overview
Amyloidosis is an infiltrative disease resulting in deposition of amyloid in the extracellular spaces of the tissues. Amyloid infiltration of the heart leads to expansion of these extracellular spaces resulting in retainment of gadolinium dye during cardiac magnetic resonance imaging. This retainment of gadolinium leads to signal enhancement in the late washout phase during delayed enhanced cardiac imaging.
MRI
CMR findings in cardiac amyloidosis include:[1]
- Signal enhancement in the late washout phase during delayed enhanced imaging
- Increased gadolinium wash-out time
- Brighter appearance of the myocardium compared to normal myocardium

CMR may be used for assessment of patients with LV dysfunction or hypertrophy or suspected forms of cardiac injury not related to ischemic heart disease. When the diagnosis is unclear, CMR may be considered to identify the etiology of cardiac dysfunction in patients presenting with heart failure, including
