Is contrast necessary for MRI?

The results of an MRI procedure without contrast are just as valuable and relevant as those done with the use of a contrast agent. MRI contrast is required when a very detailed image is necessary to evaluate the problem area of the body.

What is the difference between an MRI with and without contrast?

MRI contrast is an injectable dye used to highlight certain areas and give a more definitive diagnosis. MRI contrast is called gadolinium. It is an injectable dye. … After the without-contrast portion of your scan is completed, a simple injection of contrast is administered.

What can a brain MRI with contrast detect?

MRI can detect a variety of conditions of the brain such as cysts, tumors, bleeding, swelling, developmental and structural abnormalities, infections, inflammatory conditions, or problems with the blood vessels.
