MR Brain fMRI Neuro Protocol

Scan Notes

Last updated: 8/23/2023
Scanner preference: MR4 or MR3 only
Coil: Head

Charges:
If we acquire only the fMRI scans and the frameless scans: Charge for a 3D Recon and fMRI
If we acquire a FULL diagnostic brain in addition to fMRI: Charge for 3D Recon, fMRI and Brain WWO

 AX 3D T1 sequence:

  • AX 3D T1 NON CONTRAST acquisition must always be performed
  • Ideally the AX 3D T1 NON CONTRAST needs to match the position for all subsequent sequences (DTI, fMRI, etc.)
  • If the patient moves, repeat the AX 3D T1.
  • If you already gave gad and the patient moves, repeat the AX 3D T1 for all fMRI or DTI after it, and let the rad know.
  • If there are multiple AX 3D T1 sequences, only send the one that matches the position on DTI/fMRI to DynaSuite, PACS and archive.

SENDING IMAGES:

  • Perfusion (DSC only) - source to PACS, Clear Canvas, Intellispace
  • DWI – source to Clear Canvas
  • DTI – source to Clear Canvas and DynaSuite
  • fMRI – source/BOLD to Clear Canvas and DynaSuite
  • AX 3D T1 - PACS, Clear Canvas, DynaSuite
  • AX 3D T2 - PACS, Clear Canvas, DynaSuite

Page Neuro for the fMRI tasks and before starting the tasks.
Do not angle or add slices to task sequences.

MR4 PROCESSING:

  • Rad will draw ROIs
  • Save screenshots of the post processed graph
  • Send screen captures to Pacs and archive

MR3 PROCESSING:
Post processing not available on MR3, but you can view-only in Neuro 3D after each paradigm has completed:

  1. Highlight the pre 3D or post 3D sequence, the paradigm and associated processed sequences (MoCoSeries, Design, EvaSeries_GLM, Mean_&_t-Maps)
  2. Right-click
  3. View & Read Only
  4. Neuro 3D
  5. Auto Align (icon)
  6. Choose FMRI from the small arrow Drop Down
  7. Close when you want to open another paradigm
Plane Weighting Mode Slice Gap FAT SAT FOV Notes
AXIAL 3D T1 - None 26cm Always run pre. Ask Rad if they want another one POST. DO NOT ANGLE.Send to DynasuiteIf 3D T1 is a stereotactic, and omit padding per usual.
AXIAL DTI - None 26cm Run in conjunction with 3D T1.OK to run post gad.DO NOT ANGLE.No need for additional coverage.
AXIAL fMRIlanguage: Word Generation - None 26cm DO NOT ANGLE OR ADD SLICES
AXIAL fMRILanguage: Verb Generation - None 26cm DO NOT ANGLE OR ADD SLICES
AXIAL fMRILanguage: Sentence Completion - None 26cm DO NOT ANGLE OR ADD SLICES
AXIAL fMRIMotor: Right Finger Tap - None 26cm DO NOT ANGLE OR ADD SLICES
AXIAL fMRIMotor: Left Finger Tap - None 26cm DO NOT ANGLE OR ADD SLICES
AXIAL fMRIMotor: Breath Hold - None 26cm DO NOT ANGLE OR ADD SLICESThis sequence doesn't have a pre-built task. You must give the patient breathing instructions as the scan is run.
AXIAL fMRIMotor: Lip Movement - None 26cm DO NOT ANGLE OR ADD SLICES
AXIAL fMRIMotor: Foot Movement - None 26cm DO NOT ANGLE OR ADD SLICES
