In
this work, we present a method to accelerate MS imaging in longitudinal
studies through acquisition of fully sampled images at the baseline scan and
accelerated undersampled data at follow-ups.
W investigated feasibility to accelerate serial scanning of MS
patients with 3D pulse sequences (T2 FLAIR and T1 weighted after Gd
administration). Our results indicate
that the proposed technique has a potential to produce high-quality images from
significantly accelerated reduced follow-up acquisition (up to 8 times) and
correctly depict T2 and Gd+ lesion load and anatomical content.
