Abstract Background While using AI-assisted compressed sensing (ACS) combined with deep-learning reconstruction (DR) techniques has the potential to Shorten the acquisition time of brain T2-weighted imaging (T2WI), its imaging improvements and clinical application in brain imaging remains under explored. Purpose To evaluate the clinical feasibility of DR-ACS for brain T2-weighted imaging (T2WI), focusing on image quality, acquisition efficiency, and diagnostic accuracy, compared with the routine T2WI. Material and Methods A prospective cohort of 110 participants underwent brain MRI using three protocols at a 3.0-T MR scanner: routine T2WI, ACS-T2WI (without DR), and DR-ACS-T2WI. Subjective image quality (overall image quality, motion artifact, and diagnostic confidence, with a 5-point scale) and objective metrics (Signal-to-Noise Ratio (SNR), Contrast-to-Noise Ratio (CNR), and scan time) were compared. Statistical analysis included ANOVA and kappa. Results The overall image quality, motion artifact, and diagnostic confidence scores of DR-ACS-T2WI, assessed by two radiologists, were 4.90±0.30, 4.91±0.29 , 4.92±0.28(Reader 1) and 4.90±0.30 , 4.91±0.28, 4.91±0.30 (Reader 2), higher than those of ACS-T2WI and routine T2WI. DR-ACS-T2WI demonstrated superior SNRs in both white matter (65.06±12.1) and gray matter (97.25±18.52) compared to ACS-T2WI (47.62±8.65 and 71.54±12.05, respectively) and routine T2WI (34.32±6.51 and 51.92±8.62, respectively; P Conclusion The ACS combined with DR is clinically feasible for MRI examinations of brain diseases, offering significantly shorter image acquisition time and higher image quality compared with the routine T2WI.
