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

MRI with contrast is superior at measuring and assessing tumors. Contrast helps detect even the smallest tumors, giving the surgeon more clarity regarding the location and size of the tumor and other tissues involved. MRI images with contrast are clearer and better quality than the images without contrast.

In the study of 42 people with symptoms, brain fog and headaches lasted for more than three months in 29 people.

What does gadolinium do to the body?

Gadolinium enhances the quality of MRI by altering the magnetic properties of water molecules that are nearby in the body.
