Scan Notes:

Scan Notes:

  • P.O. Protocol
    • Patient fasting x 4-6 hours.
    • 1350 cc PO contrast ingested over 1 hour.
      • 450 cc during 0-15 min.
      • 450 cc during 15-30 min.
      • 450 cc during 30-45 min.
    • 1 cup (8 oz) WATER on table.
  • Void prior to getting on table.
  • Supine positioning
     
  • Glucagon
    • CONTRAINDICATIONS: allergy, pheochromocytoma, insulinoma.
    • 0.5 mg IM pre-imaging
    • 0.5 mg IV pre-contrast
    • Flush with sterile water IV
       
  • Send patient home with graham crackers. Encourage carbohydrates.
  • Charge for Glucagon and Gadolinium

Last updated: 1/22/2021
Charge as: Abdomen WWO
Scanner preference: MR2. Use “MRE Enterography” protocol for MR1
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.

Glucagon Injection

RAD RN to inject 1st dose of glucagon before imaging

Glucagon/Contrast injection

  • Rad Rn injects 2nd Glucagon injection 0.5 mg through IV immediately prior to connecting power injector to patient
