What do the colors mean in brain scans?

A computer uses the absorption data to show the levels of activity as a color-coded brain map, with one color (usually red) indicating more active brain areas, and another color (usually blue) indicating the less active areas.

Does MRI have color?

The majority of our scans are done in gray scale however some of our specialty exams offer color imaging as a way to aid the Radiologist using special computers.

What can you see on an MRI of the brain?

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. It can determine if a shunt is working and detect damage to the brain caused by an injury or a stroke.

What color is our brain?

The human brain color physically appears to be white, black, and red-pinkish while it is alive and pulsating. Images of pink brains are relative to its actual state. The brains we see in movies are detached from the blood and oxygen flow result to exhibit white, gray, or have a yellow shadow.

What is white on MRI?

What Are White Spots? Spots on a brain MRI are caused by changes in water content and fluid movement that occur in brain tissue when the brain cells are inflamed or damaged. These lesions are more easily seen on T2 weighted images, a term that describes the frequency (speed) of the radio impulses used during your scan.
