D) electrographic tomography.

Question

Quizplus · Accepted Answer

The technique described in which radioactively tagged chemicals are introduced into the brain and then equipment monitors where the chemicals appear in the brain is known as positron emission tomography (PET). Computerized tomography (CT) uses X-rays to provide detailed images of structures inside the body, magnetic resonance imaging (MRI) uses a strong magnetic field to produce images of structures inside the body, and electrographic tomography is not a commonly used medical imaging technique. Therefore, the best choice is B.
