Proposed epilepsy-specific MRI protocol for a high field machine

Veterinary epilepsy-specific protocol for 1.5 T MRI
Slice thickness 3 mm or less
➢ T2W – 3 sequence orientations
● Sagittal enabling identification long axis of the hippocampus
● Dorsal, perpendicular to the long axis of the hippocampus
● Transverse, parallel to the long axis of the hippocampus
➢ FLAIR 1–2 sequence orientations for hippocampal angulation
● Dorsal, perpendicular to the long axis of the hippocampus
● Transverse, parallel to the long axis of the hippocampus (optional)
➢ T1W
● 3D technique at 1 mm isotropic voxel size (if possible) or routine T1W dorsal, perpendicular to long axis of the hippocampus
● T1W post paramagnetic contrast injection enhancement if indicated by other pathology / desired by clinician
➢ Hemosiderin / calcification sensitive sequences e.g. gradient echo
● Transverse, parallel to the long axis of the hippocampus
