Clinical application of volumetric joint MR imaging has been hampered by blurring due to T2 decay. A redesigned volumetric fast spin-echo acquisition technique termed T2 shuffling corrects for T2 decay and yields effectively a four-dimensional reconstruction with varying degrees of T2 weighting. Our work assesses the clinical application of T2 shuffling for pediatric knee MRI. Our results show that T2 shuffling has the potential to suffice as a single sequence MR examination. This is especially relevant for pediatric imaging where streamlined protocols greatly improve clinical operations and patient experience.
