<h3>BACKGROUND AND PURPOSE:</h3> The use of MR imaging in emergency settings has been limited by availability, long scan times, and sensitivity to motion. This study assessed the diagnostic performance an ultrafast brain protocol for evaluation acute intracranial pathology department inpatient settings. <h3>MATERIALS METHODS:</h3> Sixty-six adult patients who underwent were included study. All both reference protocols. Both protocols consisted T1-weighted, T2/T2*-weighted, FLAIR, DWI sequences. images reconstructed using a machine-learning assisted framework. reviewed 2 blinded neuroradiologists. <h3>RESULTS:</h3> average acquisition time was 2.1 minutes 10 protocol. There 98.5% agreement on main clinical diagnosis between In head-to-head comparison, preferred terms image noise geometric distortion (<i>P </i>&lt; .05 both). ms-EPI over reduced motion artifacts .01). Overall quality not significantly different </i>&gt; .05). <h3>CONCLUSIONS:</h3> provides high accuracy evaluating while only requiring fraction time. Although there greater images, significant reduction with similar overall
