[Freesurfer] Phase encoding direction in Philips

External Email - Use Caution

Hello dear experts.

I am conducting a TBSS analysis. My MRI data was acquired by using a Philips Achieva. Since my data is derived from a Philips I am having problems accessing the acquisition parameters. Specifically I am interested in knowing the phase encoded direction. In the DICOM header it is specified "Phase encoding direction" = col, but there is no information about the direction (Anterior-Posterior/Posterior-Anterior). Based on the appearance of my data I assume this is a P-A acquisition but I would like to be sure (attached is a screenshot of my images).

Thank you very much in advance.

Benxa.
