We describe a gradient echo based imaging technique for
fast murine cardiac gated cine imaging. Using relatively
low strength gradients at 4.7T we have obtained a
multi-slice, multi-frame cine with full ventricular
coverage in just over 5 mins. These images were analysed
to assess ventricular function and the results compared
with images using a slower technique which acquired a
single line of k-space per Rwave. There was no
significant difference between the calculated left
ventricular volumes and the Fast technique led to a
reduction in flow artefacts.
