A member asked:
Is it normal to have an ejection fraction of 64% on echocardiogram and a ejection fraction of 57% on cardiac mri? with the same heart.

Yes: Perfectly normal. They're both normal. EF depends on loading conditions. It can vary - all within the normal range. Moreover, different measuring techniques will yield different results. A nuclear gated scan may find your EF is 61%. A contrast ventriculogram may find it's 59% We often simply read is as >55% to avoid the kind of concern you're having.

No worry!: The ejection fractions measured by echo and by MRI are just estimates. Both the results are close to each other and the difference is no cause for concern. Normal would be between 55 and 70% and your results are both normal and quite close to each other! relatively speaking! Good!
