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.
