T2.3.2 A Novel Diagnostic System for Cardiac Abnormalities Based On Magnetic Resonance Fluid Motion Tracking

2009 
atrial flow can be used to distinguish pre- and post-operation conditions. Results - We characterized flow patterns of blood in the human heart by analyzing the flow properties in the image. An indication of vorticity can be provided by generating histograms depicting the counts of pixels based on discrete values of vorticity labeled on a horizontal axis. The global estimation of vorticity in the segmented atrial region provides useful information on the presence of vortices within the heart chamber (Figure 1). Discussion and Conclusion - As an alternative to established medical imaging-based diagnostic techniques such as chest X-rays, and pulsed or continuous wave Doppler ultrasound scans for cardiac diagnosis, we develop a magnetic resonance imaging based approach and perform flow quantification to analyse the heart, vis-a-vis blood movement in chambers based on a measured flow field. We validate this methodology specifically for analysing flow characteristics within a human heart case study. We also demonstrate the potential for non-invasive assessment of cardiac abnormality for a pathological case of the heart. Pre-septal occlusion Post-septal occlusion
