Use 64-channel head/neck coil unless patient absolutely wont fit
If indicated for MEG and patient did not have prior SZ protocol. Replace 3D T1 MPRAGE Sag plane with AX plane. Cover vertex to upper lips. For patient

Special Instructions:
* DO NOT ANGLE; cover vertex, tip of nose, and outer ears
** Angle slices perpendicular to hippocampus; cover from ant. aspect of sella through post. aspect of corpus callosum
*** Ensure phase enc. direction is A>P
**** If 3D T2 FLAIR FS is suboptimal (blurry or grainy), perform sagittal 2D T2 FLAIR FS
***** Must be at least 2 concatenations/covers/acquisitions
Indications: new onset seizure or convulsion

#3,5,6,8
Align series #3,5,6,8 parallel with subcallosal plane
3T ONLY
#4
We must make sure that Series #4 (hippocampus T2) is aligned perpendicular to long axis of hippocampus.
First, align slices coronally by making sure sequence is exactly perpendicular to midline of patient's brain. Next, angle slices using sagittal images to cut exactly perpendicular long axis of hippocampus
See images below for guidance
If patient is under 2 years old, use 2D axial T2 FS FLAIR in place of 3D DIR and 3D T2 FLAIR

#1,2,7 Include Ears and Nose
