Table 6. Cardiac magnetic resonance imaging findings in cardiac amyloidosis.

Imaging	Findings
Cine CMR and myocardial strain	1. Left ventricular hypertrophy, symmetric or asymmetric
	2. Right ventricular hypertrophy
	3. Thicken atrial septum (≥ 6 mm)
	4. Abnormal longitudinal and circumferential strains
Late gadolinium enhancement (LGE) imaging	1. Diffuse transmural or subendocardial LGE
	2. LGE mainly occurs in the basal segments of left ventricle, right ventricle, left atrium, and atrial septum
	3. Dark blood pool pattern
T1 mapping (non-contrast)	1. Non-contrast imaging
	2. Significantly elevated T1 value
Extracellular volume (ECV)	1. Contrast is needed for this imaging
	2. Significantly elevated ECV
	3. ECV ≥ 40%

CMR, cardiac magnetic resonance; ECV, extracellular volume; LGE, late gadolinium enhancement.
