Key result
Magnetic resonance imaging of right atrial casts correlated strongly with true volumes (r = 0.99, P < 0.001), providing a reliable means to study right atrial volumes and phasic function.
Why the study?
Does cardiac-gated cine MR imaging accurately measure right atrial volumes and phasic function in cadaveric casts and healthy subjects?
Observational (n=22)

Effect estimate: r = 0.99
p-value: p=< .001
Cardiac-gated cine MR imaging is a reliable method for assessing right atrial volumes and phasic function, demonstrating that right atrial volumes are generally larger than left atrial volumes.

Validates cardiac MRI for right atrial volume research in healthy subjects; leaves open clinical adoption pending outcome data.
Järvinen et al. (1994) conducted an observational in Healthy (n=22). Magnetic resonance (MR) imaging vs. True volumes (for casts) and left atrial volumes (for subjects) was evaluated on Correlation of measured volumes of right atrial casts with true volumes (r = 0.99, p=< .001). Magnetic resonance imaging of right atrial casts correlated strongly with true volumes (r = 0.99, P < 0.001), providing a reliable means to study right atrial volumes and phasic function.
