Hi all, To make sure the L/R orientation is not flipped in the conversion and processing, I want to attach a marker on the patient's forehead. The ideal marker is the one that could show up in both MPRAGE and EPI sequence. I tried to use a Gadolinium filled syringe as a marker but it can be barely seen in MPRAGE and cannot be seen in EPI. Do you have any suggestions and tricks? Thanks a lot. -Xiaoxu
