An MRI with contrast dye, sometimes called a contrast-enhanced MRI, gives doctors a clearer picture of what’s happening inside your body. During the scan, your radiologist will inject a special dye, called a contrast agent, into your bloodstream through a cannula in your hand or arm. The dye is typically made from a metal called gadolinium, which helps highlight specific areas on MRI images.
As the gadolinium contrast dye moves through your blood, it changes how different tissues in your body respond to the magnetic field of the MRI scanner. This helps your radiologist and doctor see the finer details and get important information about your blood vessels, organs, and even growths like tumours.
Compared with a standard MRI, a contrast-enhanced MRI can pick up a lot more detail, helping your doctor tell the difference between healthy and unhealthy tissue.
