In this study, the feasibility of combining compressed
sensing (CS) with parallel MRI (pMRI) in accelerating
the T1ρ cartilage imaging is investigated. K-t ISD with
locally-adapted thresholding, named k-t LISD, combined
with JSESNE is used to reconstruct the image sequence
from undersampled data in (k, t) space. The
reconstruction process alternates iteratively between
k-t LISD for reconstruction of the image sequence and
JSENSE for sensitivity estimation. Result on in-vivo
human knee experiment shows the T1ρ quantification from
the accelerated acquisition using the proposed method is
consistent with that from full acquisition in all
cartilage compartments.
