Cine imaging or cine sequences are a type of MRI sequences acquired to capture motion.
Cine images are obtained by repeatedly imaging the area of interest for a certain time typically within a single slice, although 3D solutions already exist 3.
For the heart, this achieved by acquisition at multiple time points throughout the cardiac cycle, after synchronisation with the ECG has been achieved.
Separate k spaces are assigned to different phases or segments of the cardiac cycle.
Imaging data is acquired during the different phases of each cardiac cycle and allocated to the corresponding k-spaces. The data accretion process requires a few R-R intervals.
Images are reconstructed from each k-space and shown in a movie.
Typical clinical applications of cine imaging include:
