Question

Jack is injected with a small amount of radioactive glucose and then lies in a scanner. He is given a task--to think about his favorite song--as the scanner records the movement and location of the glucose his brain. A computer analyzes the data and produces a color-coded image of his brain activity. Jack is receiving the imaging technique called a/an ____________ scan.

positron emission tomography (PET)
functional MRI (fMRI)
electroencephalograph (EEG)
computerized tomography (CT)
