The following is an example checklist for setting up a participant in the MRI to avoid motion-related or foreign object-related artifacts:

BEFORE SCAN DATE

  • Confirm that participant does not have any MRI contraindications
  • Remind participant that any jewelry should be removed prior to the scan
  • If allowed to wear street clothes, remind participant to avoid clothing with metal or that would uncomfortable to lie in for the duration of the scan
  • If participant has indicated nervousness or history of claustrophobia, utilize mock scanner

DAY OF SCAN, PRIOR TO PARTICIPANT ARRIVAL

  • Prepare consent documents and MRI safety screener
  • Prepare scrubs and MR-compatible glasses if applicable
  • Setup scanner bed with proper headcoil, under-knee padding, neck padding, and any other padding necessary for safety and comfort
  • Check stimulus display and response device

SCAN TIME

  • Have participant fill out consent documents and MRI safety screener, and verbally confirm responses, paying attention to frequently forgotten devices and implants, like orthodontia
  • Have participant empty their pockets or change into scrubs, and remove all jewelry/hair accessories and check for any missed metallic objects with the scan center’s preferred method
  • Instruct participant on staying still and encourage them to request breaks if necessary
  • Solicit feedback on participant’s comfort while positioning them on the scanner bed and suggest ergonomic positioning of arms to avoid discomfort
  • Follow the Scan console checklist.

DURING SCAN

  • Check in with participant frequently
  • Watch for motion if you can see the participant, or use motion monitoring equipment

AFTER SCAN

  • Solicit more feedback on participant’s comfort for future sessions
  • Run MRIQC to evaluate data

Example 2

BEFORE THE SCAN DATE (1-2 days)

  • Call or email the participant before the appointment to remind them of the details and times, and confirm that they can still make it
  • Register their confirmation in STRATA or reschedule the appointment (see scheduling SOPs).
