Dr. Tang is interested in measuring the differences in brain activity between two subsets of patients as they perform a task. Which method would be the most appropriate and safest one for him to use to achieve this?

Functional magnetic resonance imaging (fMRI) is the most appropriate and safest method for measuring differences in brain activity between two subsets of patients performing a task. fMRI can noninvasively measure changes in blood flow to regions of the brain, which is an indirect measure of neural activity, and does not expose patients to ionizing radiation. The other methods listed (MRI, PET, and TMS) may be useful in other contexts, but are less suited for measuring differences in brain activity between two groups. MRI is useful for structural imaging of the brain, PET has lower spatial resolution, and TMS is typically used for targeted stimulation of specific brain regions rather than large-scale measurement of activity.
