Table 12.3-2. MRI recommendations for epilepsy neuroimaging

1. General requirements: High resolution, high contrast, complete brain coverage, optimal and thin slicing

2. Imaging can be achieved with a 2D protocol:

– T1, T2, FLAIR: Both coronal and axial planes, ≥3 mm

– T2*/SWI; contrast in selected patients

– At least for TLE: Angulation along/perpendicular to the hippocampal axis

3. Most recent recommendations (if available): 3D sequences with isotropic voxels 1×1×1 in T1 and FLAIR:

– No need for operator-dependent angulation

– Reformatting in any plane possible

FLAIR, fluid-attenuated inversion recovery; MRI, magnetic resonance imaging; SWI, susceptibility-weighted imaging; TLE, temporal lobe epilepsy.
