MR Brain + Frameless WWO Neuro Protocol - Ingenia

Scan notes:

Adjust FOV and slices to best fit the patient's age and size:

  • 0-2 years: 3mm slices / 1mm gap /small FOV
  • 2-9 years: 4mm slices / 1mm gap / smaller FOV 
  • Over 9 years and adults: 4mm slices/1mm gap / larger FOV

PATIENT PREP:

  • Earplugs only, no headphones.
  • Position sponges carefully at the level of the patient's chin if needed.

ANGLES AND COVERAGE:

  • NO ANGLES ON STEREOTACTIC SEQUENCES.
  • COVER AT LEAST 1CM ABOVE VERTEX THROUGH SKULL BASE.
  • COVER ENTIRE NOSE.

POWER INJECTION:

  • Injection Rate: 4-5mL/sec.
  • Start injection 8-10 seconds after beginning the DSC sequence.
  • For peds patients with smaller IVs, consult with Rad and peds RN or Anesthesiologist to determine a safe injection rate.

SENDING AND POST PROCESSING IMAGES:

  • Send DSC source images to PACS, Intellispace and Archive
  • Send Post Ax T1 to Intellispace
  • Post process DSC
  • Archive all sequences
