The quantity of hydrogen protons within structures being imaged by MRI has no effect on MRI contrast.

Question

Quizplus · Accepted Answer

MRI contrast is dependent on the magnetic properties of the hydrogen protons within the structures being imaged. Specifically, differences in the relaxation times (T1 and T2) of the protons in different tissues contribute to contrast in the MRI image. Therefore, the quantity of hydrogen protons in different tissues does have an effect on MRI contrast.
