Visualization of intra-cardiac 4D-flow using particle tracing with four-chamber cine images for anatomical reference, in the same subject as Figure 6. Flow is coloured blue on the right side and red on the left side of the heart. Only a small amount of particles exhibit a non-physiological flow, which was read as good image quality. No major differences were seen between 1.5 T or 3 T nor between k-t BLAST or SENSE.
