Magnetic Resonance Imaging of the Brain — Standard/Dynamic Protocol with Intravenous Contrast

What is this test?

This test is a magnetic resonance imaging (MRI) examination of the brain. Intravenous contrast, usually a gadolinium-based agent, may be used to improve the visibility of tissues, blood vessels, and areas of abnormal activity.

Why might I need this test?

A brain MRI with contrast may be ordered to investigate headaches, seizures, weakness, vision or speech changes, head injury, or suspected conditions affecting the brain. It can help assess abnormalities involving brain tissue, blood vessels, or surrounding structures.

How is the test performed?

You will lie on a padded table that moves into the MRI scanner. The technologist may place a small catheter in a vein to administer contrast, and you may be asked to remain still while several sequences of images are collected. The scanner makes loud tapping and ringing sounds, and a staff member usually provides communication or ear protection.

How do I prepare for the test?

Follow the facility's specific instructions, and tell the care team about prior contrast reactions, severe kidney disease, pregnancy, implanted medical devices, or metal in your body. Remove jewelry, watches, hairpins, and other metal items before the examination. Fasting is generally not required unless your imaging center instructs otherwise.
