Minimized Off-resonance Effects with Centric Radial SSFP for Imaging Cardiac Function
Robson M, Neubauer S
Steady-State Free Precession offers excellent contrast to noise ratio when imaging the human heart, and when used as a single slice cine acquisition is the preferred approach for imaging cardiac function clinically. Single slice centric-radial steady-state free precession (cr-SSFP) provides the shortest TR for the 2D SSFP sequence, which will minimize the off-resonance artefact sometimes seen with these sequences, especially at 3Tesla. This approach has been implemented as a cine acquisition on clinical scanner at 1.5T and 3T and is demonstrated to provide high quality images across a larger frequency range than the standard clinical Cartesian SSFP methods.
