Acoustic noise generated by MR systems represents one of the major barriers to patient comfort, particularly for the pediatric population. Reducing the slew rate of the gradient field is one way to effectively decrease acoustic noise; however, this comes at the expense of scan time. For breath-hold abdominal imaging, longer scan times mean a more stressful breath-hold for the patient, reduce temporal resolution for multi-phase imaging, and may allow for more motion artifact due to suboptimal breath-holding. This work describes an accelerated 3D multi-phase technique compatible with fat saturation for both quiet and motion-robust abdominal imaging.
