  Injection ParametersLab Requirements

  Parameter	Value
  Agent	Omnipaque 350
  Volume	125 mL
  Flow Rate	3 mL/s

  Use full dose if GFR > 30

  If GFR < 30

  Max Contrast = \(2*\left[\frac{\text{Patient Weight}}{75 \text{ kg}} * \text{eGFR}\right]\)

  Technologist NotesNursing NotesRadiologist NotesTips & Tricks

  • Portal venous phase 70s. SINGLE PHASE to minimize fetal radiation. Shield uterus if injury distant. Document weeks gestation

  • Pregnancy documented. Fetal heart tones if equipment available. Shield if possible

  Safety First

  • Renal Function: Check if known
  • Allergy: Trauma indication documented

  • Assess maternal injuries. Minimize fetal radiation exposure. Document placental injury if visible

  • Document gestational age. Shield fetus if possible. Minimize radiation
