Libby's physician refers her to a medical centre in order to have the biochemical activity in her brain analyzed. She is given an injection of a glucose-like substance containing a radioactive element and her brain is then scanned. The technique being used is called:
A) positron-emission tomography.
B) functional magnetic resonance imaging.
C) the lesion method.
D) electroencephalography.

Question

Quizplus · Accepted Answer

The technique described involves injecting a glucose-like substance with a radioactive element and scanning the brain, which is consistent with the use of positron-emission tomography (PET) imaging. Functional magnetic resonance imaging (fMRI) measures changes in blood oxygen levels in the brain and does not involve the injection of a radioactive substance. The lesion method involves studying the effects of brain damage, and electroencephalography (EEG) measures electrical activity in the brain but does not involve injection of a substance or scanning.
