Global left ventricular function quantification with CMR 4D Flow
Background 4D MR flow is a rapidly evolving technique, offering both anatomical and functional information in just a single acquisition and if successful, in the future, the 4D flow sequence should replace the 2D MR sequences. The purpose of this study is to use the anatomical information from the 4D flow sequence to assess the global left ventricular function and compare these results with the...

متن کاملSemi-automatic quantification of 4D left ventricular blood flow
BACKGROUND The beating heart is the generator of blood flow through the cardiovascular system. Within the heart's own chambers, normal complex blood flow patterns can be disturbed by diseases. Methods for the quantification of intra-cardiac blood flow, with its 4D (3D+time) nature, are lacking. We sought to develop and validate a novel semi-automatic analysis approach that integrates flow and m...
متن کاملRemote CMR 4D Flow Quantification of Pulmonary Flow
Background 4D MR flow has shown to have advantages over standard cardiac magnetic resonance (CMR), offering both anatomical and functional information in just a single acquisition. Pulmonary stenosis and pulmonary regurgitation are common problems in follow-up of patients with congenital heart disease. In this study we tested flow quantification at the level of the pulmonary valve (forward and ...
متن کامل4D flow CMR can detect subtle right ventricular dysfunction in primary left ventricular disease
Background Right ventricular (RV) function holds important prognostic value in both rightand left-sided acquired and congenital heart diseases. However, assessment of RV function remains challenging due to its complex chamber geometry and physiology. 4D flow CMR permits assessment of multidimensional intraventricular flow. We hypothesized that 4D flow specific markers of RV function can detect ...
