Table 4.

Disagreements between 3 experienced observers for diagnosis of myocardial hemorrhage based on MRI.*

Disagreement vs. Observer 1 Observer 2 Observer 3
T2-weighted MRI 6 4 2
Kappa statistic 0.94 0.89 1.00
LGE MRI 2 2 0
Kappa statistic 1.0 0.92 0.97
EGE MRI 4 4 0
Kappa statistic 1.0 0.88 1.0

EGE = Early gadolinium enhanced MRI; Late gadolinium enhanced MRI.
