A free-breathing 2D pseudo-golden-angle spiral phase-contrast sequence was modified to listen for image-quality messages from the reconstructions. Ten healthy volunteers and 1 patient were imaged at 0.55 T. Target SNR was selected based on retrospective analysis of cardiac output error, and performance of the automatic SNR-driven "stop" was aMagnetic resonance in medicineInline automatic quality control of 2D phase-contrast flow MRI for subject-specific scan time adaptation.PMC11142871ZIA-HL006257ZIA-HL006213ZIA HL006213ZIA HL006257ZIA‐HL006257ZIA‐HL006213Daude PCampbell-Washburn AELederman RJRamasawmy RChow KJaved AfalseInline automatic quality control of 2D phase-contrast flow MRI for subject-specific scan time adaptation.<h4>Purpose</h4>To develop an inline automatic quality control to achieve consistent diagnostic image quality with subject-specific scan time, and to demonstrate this method for 2D phase-contrast flow MRI to reach a predetermined SNR.<h4>Methods</h4>We designed a closed-loop feedback framework between image reconstruction and data acquisition to intermittently check SNR (every 20 s) and automatically stop the acquisition when a target SNR is achieved.
