- Images must be checked by radiologist or radiology resident before the patient gets off the table.
- Please do mDixon subtractions (subtraction = each of 3 post-contrast phases – pre-contrast sequence)
- Always acquire in AXIAL and CORONAL planes (to distinguish true abnormalities from artifact).
- M2D = multiple 2D (multiple single slice acquisition, with single slices scanned in sequential order)
- Images must be checked by radiologist or radiology resident before patient leaves.
- *Over-contiguous images.
