Which technique of studying the brain involves injecting the ?patient with radioactive glucose?

A) EEG
B) CT
C) MRI
D) PET

PET (positron emission tomography) involves injecting the patient with radioactive glucose and then tracking the location of the glucose in the brain as it is metabolized. A computer then creates an image of the brain based on the glucose activity. EEG (electroencephalography) measures electrical activity in the brain through electrodes placed on the scalp. CT (computed tomography) uses X-rays to create images of the brain. MRI (magnetic resonance imaging) uses a magnetic field and radio waves to create detailed images of the brain.
