BackgroundAdministration of gadolinium-contrast can cause problems in cardiac amyloidosis (CA) patients with impaired renal function.PurposeTo compare patterns of cardiovascular magnetic resonance tissue tracking (CMR-TT) for CA and hypertrophic cardiomyopathy (HCM) and to assess the feasibility of CMR-TT to distinguish between these diseases without administration of gadolinium-contrast.Material and MethodsIncluded were 54 patients with biopsy-proven CA, 40 patients with HCM, and 30 healthy people. We calculated strain ratio of apex to base (SRAB) in the left ventricle...
