    • CONTRAINDICATIONS: allergy, pheochromocytoma, insulinoma.
    • 0.5 mg IM pre-imaging
    • 0.5 mg IV pre-contrast
    • Flush with sterile water IV

  • Charge for Glucagon and Gadolinium

Last updated: 4/12/19
Charge as: Abdomen W/WO
Scanner preference: MR1. Use “Large Bore” protocol for MR2
Coil: Torso Coil
Contrast: Gad and Glucagon

Breath Holds:

  • Scan on expiration.
  • Monitor that patient is breath-holding. Breathe the patient slowly so they have time to follow instructions. Do not start scan until the patient has stopped breathing.
  • Give 2L O2 if it will help with breath-holds UNLESS PATIENT HAS COPD OR ANOTHER REASON NOT TO GIVE O2.
