Interactive Checklist

Answer the questions in order. The checklist applies ACR, CBR and ACOG criteria for contrast use in pregnant and lactating women.

Understand the recommendation

Iodinated and gadolinium contrast in pregnancy and lactation

The recommendation changes depending on the scenario (pregnant or lactating) and contrast type (iodinated or gadolinium). Practical summary based on ACR, CBR, and ACOG:

Pregnant + iodinated contrast

ACR does not recommend withholding iodinated contrast in pregnant women when necessary for diagnostic purposes. Document clinical justification and consent.

Pregnancy: iodinated contrast may be administered when clinically necessary and when diagnostic benefit outweighs theoretical risks, with documented justification.

Pregnant + gadolinium

Exceptional use: discuss risk/benefit and obtain consent. When necessary, prefer more stable agents (Group II, predominantly macrocyclic) and the lowest diagnostic dose possible.

Pregnancy: routine gadolinium should be avoided; consider only in exceptional situations, with relevant clinical benefit and shared decision-making.

Lactating + iodinated contrast

Interruption of breastfeeding is not necessary after intravenous iodinated contrast.

Breastfeeding: no need to interrupt after intravenous iodinated contrast.

Lactating + gadolinium

Interruption of breastfeeding is generally not necessary after gadolinium-based contrast — less than 0.04% of the maternal dose is excreted in milk.

Breastfeeding: generally no need to interrupt after gadolinium-based contrast.

Premedication for prior allergic reaction

Patient with history of allergic reaction to contrast: premedication is recommended per institutional protocol. Do not omit premedication when indicated.

Outside pregnancy/lactation

For non-pregnant and non-lactating patients, use the institutional routine contrast protocol.

Common questions

Frequently asked questions about contrast in pregnancy and lactation

Should iodinated contrast be withheld from a pregnant patient who needs a diagnostic exam?+
No. ACR does not recommend withholding iodinated contrast in pregnant women when necessary for diagnostic purposes — document clinical justification and consent.
Can gadolinium be used in pregnant patients?+
Only as an exceptional use: discuss risk/benefit and obtain consent. When necessary, prefer more stable agents (Group II, predominantly macrocyclic) and the lowest diagnostic dose possible.
Does breastfeeding need to be interrupted after iodinated contrast?+
No. ACR and other guidelines indicate that interruption of breastfeeding is not necessary after intravenous iodinated contrast.
Does breastfeeding need to be interrupted after gadolinium?+
Generally not. Less than 0.04% of the maternal dose is excreted in milk, and ACR indicates that breastfeeding interruption is generally not necessary after gadolinium.
Does a patient with a history of contrast allergy need any extra precaution?+
Yes — premedication is recommended per institutional protocol. Premedication should not be omitted when indicated.
