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.
