Silent T1-weighted head scanning using the PETRA sequence is investigated in this work. Inversion pulses are used to enhance the T1 contrast. Optimization of the settings for the inversion and waiting times are performed by simulation and volunteer scans. The in-vivo results show that the PETRA sequence generates image quality, SNR and CNR between grey and white brain matter comparable to the MPRAGE sequence. Without the need of hardware changes, PETRA might be a silent substitute for the MPRAGE sequence in many applications.
