What is this test?

This is an MRI scan of the chest and abdomen performed with intravenous (IV) contrast. MRI uses magnetic fields and radio waves to create detailed pictures, while the contrast helps highlight blood flow and certain tissues.

Why might I need this test?

Your doctor may order this scan to investigate unexplained symptoms or evaluate organs, blood vessels, or areas affected by injury, infection, or inflammation. It may also be used to monitor certain conditions or treatment.

How is the test performed?

You will lie on a table that moves into the MRI scanner. IV contrast is usually injected through a vein in your arm, and images are taken while you remain still. The scan may be noisy and can take 30 to 60 minutes or longer.

How do I prepare for the test?

Follow your imaging center's instructions, and tell the staff about any prior contrast reaction, kidney disease, implanted devices, or metal in your body. Tell the team if you are pregnant or may be pregnant, and ask whether any medications, such as metformin, require special handling.

Frequently asked questions

Does this MRI use radiation?
No. MRI uses magnetic fields and radio waves rather than ionizing radiation, although IV contrast is administered for this examination.
Will I feel the IV contrast?
You may feel a brief cool sensation or pressure when it is injected. Serious reactions are uncommon, but tell the staff about any previous contrast reaction before the scan.
What if I have a metal implant or am pregnant?
Many medical implants and metal objects can be safely scanned, but the MRI team must review them beforehand. Notify the staff if you are pregnant or could be pregnant because the scan may need to be changed or postponed.
