After injection
The imaging team observes the patient for at least 30 minutes
Product availability
The selected eMC product is marked as discontinued
What is gadopentetic acid dimeglumine salt used for?
The selected product is licensed for diagnostic contrast enhancement in direct magnetic resonance arthrography.
Making a joint and surrounding structures clearer on MRI to support diagnosis in adults.
How does gadopentetic acid dimeglumine salt work?
The gadolinium chelate alters the relaxation of nearby water protons within the joint, increasing signal on suitable MRI sequences so joint spaces and structural abnormalities stand out more clearly.
How to take gadopentetic acid dimeglumine salt
Radiology staff inject it directly into the joint while the patient sits or lies down. Scanning may begin immediately, followed by observation for possible reactions. Do not drive if temporary joint discomfort or restricted movement makes driving unsafe.
It is not swallowed, self-injected or given into a vein.
Follow the imaging department’s preparation and aftercare instructions.
gadopentetic acid dimeglumine salt side effects
Common or expected effects
- Pain, pressure or temporary discomfort in the injected joint or at the injection site.
Get urgent medical advice
- Breathing or swallowing difficulty, facial or throat swelling, widespread hives, severe dizziness, fainting or collapse may indicate hypersensitivity or shock.

gadopentetic acid dimeglumine salt in pregnancy
Gadopentetic acid can cross the placenta, and its effects on the baby are uncertain. Tell the radiology team if you are pregnant, might be pregnant or are planning pregnancy so they can assess the need for contrast and alternative imaging options.
gadopentetic acid dimeglumine salt while breastfeeding
Only negligible or undetectable amounts have been found in breast milk, and infant absorption is expected to be very low. Breastfeeding interruption is generally unnecessary after gadolinium contrast, although individual advice matters for premature or unwell infants.
gadopentetic acid dimeglumine salt interactions
No specific clinically important medicine interactions are identified for this intra-articular formulation. Tell radiology staff about all medicines and previous reactions to contrast agents.
