Phase Encoding Direction-AP/PA Question

,
1

Hi all,

I’m seeing conflicting reports on here for phase encoding direction and I just wanted to confirm with someone that I’m interpreting it correctly with regards to BIDS formatting.

AP directionality the phase encoding direction in the json file should be j-
PA directionality the phase encoding direction in the json file should be j

Thanks.

Hi @Steven,

Would you be able to answer the question above. Not sure if I asked the question in the right place.

Thanks.
