In the ________ procedure, a composite picture of brain activity is produced by sensing which areas of the brain show the highest concentration of a low-level radioactive glucose.

Question

Quizplus · Accepted Answer

The procedure described in the question refers to PET (positron emission tomography). PET uses low-level radioactive tracers, such as glucose, to detect brain activity. The areas of the brain with higher activity will show a higher concentration of the tracer, which is then detected by the PET scanner to produce a composite image of brain activity. CT and MRI are imaging techniques that produce detailed pictures of the brain's structure, while EEG and fMRI measure brain activity in different ways.
