Table 3 Intraclass correlation coefficients for each measured variable between each of the 3 CMR readers. Values greater than 0.9 reflect excellent agreement. Inter-rater agreement is very strong

From: Normal right and left ventricular volumes prospectively obtained from cardiovascular magnetic resonance in awake, healthy, 0- 12 year old children
