PROPELLER imaging is the choice for motion-prone anatomies, to generate good diagnostic quality images even for challenging patients. However, it is associated with prolonged scan times. In this study we evaluate the application of a new DL-based reconstruction algorithm to enhance a fast PROPELLER shoulder protocol with the goal of providing consistent diagnostic confidence and an overall improved image quality compared to conventional routine protocols. Our study demonstrates the proposed under 10min shoulder MRI protocols are interchangeable and have the same diagnostic confidence with better SNR and lesion conspicuity than routine MRI protocols for shoulder post-contrast and instability exams.
