3D fusion echocardiography improves 3D left ventricular assessment: comparison with 2D contrast echocardiography

Left ventricular volume and ejection fraction assessment with transoesophageal echocardiography: 2D vs 3D imaging.

BACKGROUND Developments in transducer technology have enabled the use of three-dimensional transoesophageal echocardiography (3D TOE) in the operating theatre. Transthoracic echocardiography (TTE) 3D left ventricular (LV) volumes and ejection fraction (EF) agree better with magnetic resonance imaging (MRI) measurements, with less intra- and inter-observer variability compared with 2D. This has ...

3D Myocardial Contrast Echocardiography

Live 3D echocardiography: a replacement for traditional 2D echocardiography?

OBJECTIVE We describe the development of real-time 3D imaging and review the previously used versions of 3D echocardiography so that the reader will appreciate why current developments truly do represent a quantum leap in the technology. CONCLUSION Three-dimensional echocardiography has now been shown to have several advantages over 2D echocardiography, particularly for volume measurements, v...

Estimation of 3D left ventricular deformation from echocardiography

The quantitative estimation of regional cardiac deformation from 3D image sequences has important clinical implications for the assessment of viability in the heart wall. Such estimates have so far been obtained almost exclusively from Magnetic Resonance (MR) images, specifically MR tagging. In this paper we describe a methodology for estimating cardiac deformations from 3D echocardiography (3D...

Left atrial volume: comparison of 2D and 3D transthoracic echocardiography with ECG-gated CT angiography.

RATIONALE AND OBJECTIVES Left atrial volume (LAV) measurement by conventional two-dimensional (2D) transthoracic echocardiography (TTE) may be limited by the geometric model, by suboptimal definition of left atrial endocardium, or by chamber foreshortening. Three-dimensional (3D) TTE is posited to eliminate chamber foreshortening, and LAV measurement by 3D TTE should be more reflective of true ...
