 Post Processing

MPRs

Sagittal and coronal

Use 1 @ 0.5

D Filter data

Recon 2 @ 1

 Archiving

Without IV Contrast	2 @ 1 1 @ 0.5	D Filter B Filte
Contrast	2 @ 1 1 @ 0.5	D Filter B Filter
MPR's	2 @ 1	D Filter

 

Notes:

Use thinnest set of recons available to do MPRs (i.e. in large patients 2 @ 1).
