Valves and coronary vessels remain difficult to observe
in low resolution dynamic cine MR images. High
resolution cardiac cine MRI implies a long acquisition
time requiring free breathing which leads to breathing
motion artifacts. Cine-GRICS reconstructs motion
compensated images using physiological sensors. On six
volunteers, series of 5mm thickness 384x384 free
breathing cine images covering the heart in anatomical
orientations have been acquired at 3T. Despite contrast
change due to long TR in high resolution SSFP, expected
anatomical details could be observed. A high resolution
protocol covering the heart with cine images was
performed in less than one hour.
