Retrospective real-time cine with improved temporal resolution can enhance the visualization of valve. In this 3CH slice, the mitral valve is well captured in both real-time reconstruction (b) and segmented cine (c). The image quality of raw real-time cine (a) is much worse than the retrospective reconstruction. (d) shows the intensity profiles across time for the retrospective real-time and segmented cine. The intensity profile of raw real-time cine is generated by interpolating all images acquired in one cardiac cycle. The trigger time of raw real-time cine is 342 ms and for retro-gated reconstruction (b and c), it is the 7th cardiac phase out of 30 with the approximated trigger time of 395 ms.
