DL-accelerated shoulder MRI cuts scan time 38.7% but may underdetect bursitis and supraspinatus tears

Sonic DL reduced nominal acquisition time by 38.7% (6:15 vs 10:12 min:s) vs AIR Recon DL in shoulder MRI, but subacromial/subdeltoid bursitis and supraspinatus tears were detected less often (P=0.049, P=0.006) in a pilot of 30 patients.

• Artifact was slightly worse on routine (AIR Recon DL) exams (score 3.20 vs 3.37, P=0.039); image quality, sharpness, and SNR did not differ significantly (P 0.171–0.861).
• Diagnostic equivalence was not established; a larger powered study is needed to fully evaluate diagnostic performance.
