The study aim was to explore the diagnostic value of ECV for cardiac amyloidosis calculated by 5 min post-contrast T1-mapping compared with conventional 15-20 min post-contrast T1 mapping. The results showed ECV calculated by 5min post-contrast T1 mapping had similarly promising diagnosis value for cardiac amyloidosis compared with 15-20 min post-contrast T1 mapping.
