AI-assisted techniques reduce knee MRI scan time while maintaining image quality in patients, suggesting improved comfort.
Motivation: Develop an advanced accelerated scan protocol to enhance the efficiency and feasibility of knee MRI for more patients. Goal(s): Based on ACS and MultiBand technology, the MRI scan time of knee joint can be reduced without compromising the diagnostic value of image. Approach: Evaluate 25 patients using ACS, ACS Multiband, and PPA protocols on a PET/MR system. Compare image quality through subjective assessments and objective analyses (SNRs and CNRs). Results: ACS and ACS Multiband protocols maintained comparable image quality and diagnostic value while significantly reducing scan times. Despite slight regional SNR reductions, they demonstrated higher SNR in critical structures compared to PPA. Impact: ACS Multiband and ACS improve MRI efficiency and patient comfort while preserving diagnostic quality
