Question

Quizplus · Accepted Answer

The major difference between MRI and fMRI is that fMRI measures brain activity while tasks are performed, whereas MRI only provides a structural image of the brain. Option A is incorrect because both MRI and fMRI take multiple pictures of the brain from different angles. Option C is incorrect because neither MRI nor fMRI uses X-rays. Option D is incorrect as fMRI does involve measuring the concentration of oxygenated hemoglobin, but not in relation to voxels.
