Contrast enhanced T1 imaging has been used to aid in the detection of the fibrous cap overlying the necrotic core. We have implemented 3D SOS with retrospective cardiac cycle gated compressed sensing reconstruction to minimize, characterize artifacts in post-contrast imaging. Radial based k-space trajectory may offer reduced motion sensitivity and more robust ciné-ROCS reconstructions due to its inherent oversampling of central k-space. Ciné-ROCS reconstruction from 3D SOS acquisition demonstrates improved demonstration of fine plaque structures and vessel wall movement due to cardiac motion to the regular reconstruction and may help provide information on symptomatic plaque development and response to treatment.
