Table 1 Comparison of average peak and TTP velocities between TPM MRI and STE. (TTP - time to peak; TPM - tissue phase mapping; STE - speckle tracking echo; Std - standard deviation).

From: Co-registered MR tissue phase mapping and speckle tracking echocardiography: inter-modality comparison of regional myocardial velocities in pediatric patients
