Key result
Cardiac magnetic resonance measurements of right ventricular volume and stroke volume demonstrated high interobserver (ICC 0.94-0.99) and intraobserver (ICC 0.96-0.99) reproducibility.
Why the study?
What is the inter- and intraobserver reproducibility of CMR-derived measurements of right ventricular size and function in patients with normal and dilated ventricles?
Population
60 patients in three groups: normal right ventricle, right ventricular dilation due to atrial septal defect…
Comparison
Cardiac magnetic resonance-derived measurements… vs Inter- and intraobserver comparisons.
Design
Cross-sectional, Two independent observers analyzed each study.

CMR RV volume measurements show high reproducibility across groups; supports research standardization but leaves EF and mass metrics less certain for practice.
Observational (n=60)
What is the inter- and intraobserver reproducibility of CMR-derived measurements of right ventricular size and function in patients with normal and dilated ventricles?
Effect estimate: ICC 0.94-0.99
Cardiac magnetic resonance provides highly reproducible measurements of right ventricular size and function, comparable to left ventricular measurements, in patients with both normal and dilated right ventricles.
Mooij et al. (2008) conducted an observational in Normal and dilated right ventricles (n=60). Cardiac magnetic resonance (CMR) vs. Inter- and intraobserver comparisons was evaluated on Inter- and intraobserver reproducibility of biventricular mass, volume, ejection fraction, and stroke volume (ICC 0.94-0.99). Cardiac magnetic resonance measurements of right ventricular volume and stroke volume demonstrated high interobserver (ICC 0.94-0.99) and intraobserver (ICC 0.96-0.99) reproducibility.
