MRCP or ERCP: Imaging the Ducts and Treating a Finding

If the letters MRCP and ERCP have appeared in your care plan, ask the clinician to write out which appointment you are being offered. Then ask what the team hopes to learn or treat during it.

What changes between the procedures?

Question	MRCP	ERCP
How is it performed?	MRI-based imaging.	An endoscope passes through the mouth to the duodenum; dye permits detailed X-ray pictures of the biliary tree.
What is its role?	A detailed scan of the bile duct and pancreas.	Imaging with the possibility of removing stones or placing a drainage stent.
How can they fit together?	May be performed before, or sometimes instead of, ERCP.	May be part of the plan when a procedure is needed.

This comparison draws on Leicester’s investigation leaflet.¹

Ask why the recommended procedure fits your findings. If both appear in the plan, ask what the team needs from each and whether the first result could change the next step.

Settle the purpose before arranging the day

You could say: “Is this appointment intended to obtain images, carry out treatment, or both? What finding are we trying to address?”

Ask the clinician to explain the expected benefits, risks and alternatives for your own circumstances. If you have had another scan already, ask what question remains. Bring the report if the service does not already have it.

Leicester describes ERCP as usually performed under sedation, and says procedure-specific information is sent with the appointment letter.¹

Follow the instructions for your own appointment. Ask the unit to clarify food, drink and medicine instructions before making changes. Confirm what support or transport you need afterward and how much time to allow. Tell the team about any previous difficulty with a procedure that you want discussed.

Keep the result and follow-up plan together

Ask who will explain the findings, when that discussion should happen and whom to contact if the expected appointment or message does not arrive. Write the contact details beside the procedure name.

If treatment is being considered during ERCP, ask what the team expects to do and what would happen if the finding differs from the plan. Ask for the recovery instructions and the changes that should prompt contact with the service.

At the result discussion, return to the question behind the referral. Ask what has been answered, whether another investigation or treatment is being recommended and why.
