Updated extended HARNESS epilepsy-specific protocol.

A: Core Sequences	B: Additional Sequences with Evidence of Gain
isotropic sagittal ≤ 1 mm 3D T1 sequ. eg MPRAGE	isotropic sagittal ≤ 1 mm 3D T1 IR sequ. eg MP2RAGE (may replace MPRAGE)
isotropic sagittal ≤ 1 mm 3D FLAIR sequ. no interslice gap	axial hemosiderin sensitive susceptability weighted sequ. SWI displayed as MIP
high resolution (e.g., 0.4 × 0.4 × < 2 mm) coronal 2D T2 images	diffusion weighted sequ. DWI 2.5–3 mm when deemed appropriate by change of semiology/seizure frequency ± MR lesion:
	isotropic ≤ 1 mm 3D T1 MPRAGE Gd enhanced (0.2 mmol/KG)
