Mesenteric artery duplex

Looking at the arteries that feed your digestive organs.

Mesenteric artery duplex evaluates blood flow in the arteries supplying the digestive organs. Fasting may be required, and a post-meal comparison may be performed if ordered.

What it looks for

  • Narrowing where each artery leaves the aorta
  • Flow speeds at the origins of the coeliac and mesenteric arteries
  • Whether the coeliac artery flow changes as you breathe in and out
  • How the waveform responds after a meal, if a post-meal study was ordered

Exam information

Common questions.

Additional information about the procedure and your visit.

When can I eat after the exam?

Confirm with the sonographer that all measurements are complete before eating, particularly if a post-meal comparison is planned.

Will I receive breathing instructions?

The sonographer may ask you to adjust your breathing while obtaining images and flow measurements.

How will I receive my results?

A clinician reviews the images and measurements to prepare a report. The practice will publish its results and report-delivery process before appointments become available.

Getting ready

Before you come in.

Fasting may be required.

Instructions sent with your appointment take priority over anything on this page, even where the two differ.

Afterwards

When it is over.

The gel is wiped off and you can eat normally, unless you have been asked to stay for a post-meal comparison.

The practice will publish who interprets the study and how results are shared after its reporting workflow is approved.
