Suppose you are investigating neurological function, and one of the initial portions of your procedure is to inject radioactive oxygen-15 into the patient's bloodstream. Which of the following methods are you most likely using to measure neurological activity?
A)electroencephalography (EEG)
B)computerized axial tomography (CAT)
C)positron emission tomography (PET)
D)magnetic resonance imaging (MRI)

Positron Emission Tomography (PET) is the method that uses the injection of radioactive tracers (such as oxygen-15) to measure metabolic activity in the brain. The tracer emits particles that are detected by the PET scanner, and the resulting images indicate areas of the brain that are metabolically active. EEG measures electrical activity in the brain, while CAT and MRI use radiation and magnetic fields to create detailed structural images of the brain but do not directly measure metabolic activity.
