Cardiovascular magnetic resonance imaging for amyloidosis: The state-of-the-art

Amyloidosis results from insoluble precursor proteins being deposited in the extracellular compartment. The prognosis of the disease is predominantly determined by cardiac involvement due to amyloid accumulation that contributes to cardiac dysfunction and disturbed conduction of cardiac electrical signals. The clinical and radiological manifestations of amyloidosis are often non-specific, making amyloidosis a diagnostic challenge both for clinicians and radiologists. Cardiovascular magnetic resonance imaging, including conventional sequences, late gadolinium enhancement, T1 mapping and determination of extracellular volume fraction is a multi-dimensional modality for the assessment and diagnosis of cardiac amyloidosis and, in addition, is an excellent tool for risk stratification and disease tracking.
