In what way are H 2 15 0 PET imaging and fMRI different?

fMRI measures changes in blood flow and oxygenation as a proxy for neural activity, which is considered an intrinsic signal. PET imaging, on the other hand, requires the introduction of a radioactive tracer (a contrast agent) into the body to measure metabolic processes, making B the correct choice.
