Sequence‐based acoustic noise reduction of clinical MRI scans

Clinical MRI patients typically experience elevated acoustic noise levels of 80–110 dB(A). In this study, standard clinical turbo spin echo (TSE) and gradient echo (GRE) sequences were optimized for reduced acoustic noise at preserved diagnostic image quality.
