By detecting the subatomic particles emitted by weakly radioactive glucose as it is consumed by the brain, researchers can obtain detailed images of activity both near the surface and below the surface of the brain. This technique is called a(n)
A) ablation.
B) PET scan.
C) MRI scan.
D) CT scan.

Quizplus · Accepted Answer

A PET (Positron Emission Tomography) scan involves the use of a radioactive tracer (in this case, radioactive glucose) to visualize and measure changes in metabolic processes, and is particularly useful for examining brain activity.
