Table 6 Proposed epilepsy-specific MRI protocol for a high field machine

From: International Veterinary Epilepsy Task Force recommendations for a veterinary epilepsy-specific MRI protocol

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
