Hello,
My question is regarding oxford_asl command line.
I try to combine csf mask (actually, it's just ventricles) in the cbf quantification. However, it outputs exactly the same results with or without the csf mask.
My command line with the mask is:
oxford_asl -i n_1/pwi_n_af_fil_1.nii.gz -o n_1/cbf_1 -c m0/m0_mean --bolus 0.7 --t1 2 --t1b 2.2 --tis 1.5 --cmethod voxel --t1t 2 --tr 10.0 --bat 0.8 --vars --csf vent_mask
Without the mask, I simply remove the csf option:
oxford_asl -i n_1/pwi_n_af_fil_1.nii.gz -o n_1/cbf_1 -c m0/m0_mean --bolus 0.7 --t1 2 --t1b 2.2 --tis 1.5 --cmethod voxel --t1t 2 --tr 10.0 --bat 0.8 --vars
I also tried using a structural image, as it is mentioned that csf mask will be automatically extracted from it:
oxford_asl -i n_1/pwi_n_af_fil_1.nii.gz -o n_1/cbf_1 -c m0/m0_mean --bolus 0.7 --t1 2 --t1b 2.2 --tis 1.5 --cmethod voxel --t1t 2 --tr 10.0 --bat 0.8 --vars -s phys_fil_1/ant_uni_b
Supposing those different inputs are used in the calculation, how come do I get the same results for all three?
Thank you,
Avner
