Knowledge-based reconstruction for measurement of right ventricular volumes on cardiovascular magnetic resonance images in a mixed population

Abstract

A systematic difference (overestimation) was noted for right ventricular size as assessed with knowledge-based reconstruction compared with conventional methods for analysis. Observer variability for the new method was comparable to what has been reported for the right ventricle in children and congenital heart disease with conventional analysis.

The right ventricle in volume or pressure overload : Insights from novel imaging techniques

“…We found that KBR consistently underestimated RV volumes by a small amount. In a recently published study by Pieterman [109], KBR overestimated RV volumes. The largest difference in the previous study was in patients with right ventricle-pulmonary artery (RV-PA) pathology, a group whose anatomy is difficult to visualize.…”
