Cine imaging (MRI)

Last revised by Andrew Murphy on 23 Mar 2023

Cine imaging, a.k.a. cine sequences or cine MRI, are a type of MRI sequence acquired to capture motion.

Imaging technique

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 is 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.

This type of imaging technique requires fast imaging techniques using very short repetition and echo times such as balanced steady-state free precession or spoiled gradient echo sequences 1,2.

Clinical applications

Typical clinical applications of cine imaging include:
