Sound levels in MRI can be reduced by switching a silent gradient axis beyond the hearing threshold. In this work, we implemented a silent readout module that applies such a silent gradient axis (at 7T) to a 3D MPRAGE sequence. This resulted in a sequence that featured a much lower peak sound level (26 dB reduction), similar image contrast and imaging time compared to a conventional MPRAGE-scan. This shows that a silent gradient axis provides a pathway to fast and quiet brain imaging with the potential to translate to other field strengths.
