Knowledge-Based Reconstruction of Right Ventricular Volumes Using Real-time Three-dimensional Echocardiographic as Well as Cardiac Magnetic Resonance Images: Comparison With a Cardiac Magnetic Resonance Standard

摘要

Background: Right ventricular volume quantification using real-time three-dimensional echocardiographic (RT3DE) imaging is limited by technical shortcomings of acquisition and quantification. In this study, a two-step approach was used to overcome these limitations. First, a modified acquisition technique for RT3DE imaging was applied, and second, a software tool using knowledge-based reconstruction (KBR) was used. The approach was validated against the gold standard, cardiac magnetic resonance (CMR) imaging, using CMR and RT3DE data sets from healthy children and from patients with congenital heart disease.
