CINE and delayed enhancement imaging are widely used in
cardiac MRI to evaluate function and viability,
respectively. In this work, we demonstrate a new
technique to acquire both function and viability in a
short breath-hold of 4 seconds. The technique is based
on highly-accelerated IR real-time CINE 2D bSSFP using
compressed sensing to produce images with high spatial
and temporal resolution. Subsequently, a registration
and motion-propagation strategy is used to reconstruct
CINE series for each of the acquired TI-contrasts. Based
on multi-TI CINE series, it is possible to
retrospectively visualize any TI-contrast as CINE or to
reconstruct CINE pseudo-T1 maps.
