MRI is pivotal in the assessment of shoulder disorders because of its excellent soft-tissue contrast. Recently studies have demonstrated the potential of quantitative maps acquired using a multi-echo spin-echo (MESE) sequence for the diagnosis of shoulder osteoarthritis and supraspinatus tendinosis [1,2]. However, the long examination time for MR assessments is a burden for patients. To reduce the scan time, rapid imaging techniques such as parallel imaging, compressed sensing, and deep-learning…
