Describe what is the following imaging techniques can be used for. Although there is some overlap, choose the answer that best describes each technique.

Techniques:

___ MRI (magnetic resonance imaging)

___ fMRI (functional magnetic resonance imaging)

___ PET (positron emission tomography)

___ CT or CAT (computerized tomography)

____ EEG (electroencephalography)

Although some my overlap, match the following statements that best describes the techniques shown above.

A. This technique allows indirect, general localization during the performance of tasks. It offers very low spatial resolution data, but it's high temporal resolution means is useful for measuring changes in brain activity during different tasks.

B. Although the resolution is low, this technique is helpful for detecting large abnormalities (e.g., lesions, tumors). Other imaging techniques are required for better resolution or diagnosis.

C. This technique can produce multidimensional images of the inside of the brain, showing not only the visual representation of neuroanatomical structures, but also their functional abilities during active times (e.g., cancerous cells consume more energy, and thus are easy to detect using this technique).

D. This technique can be used to explore how the brain changes activity during different tasks, with reasonable strong spatial resolution and somewhat poor temporal resolution.

E. This can be used for visualizing abnormalities in the brain and spinal cord such as tumors, and can detect changes in metabolic intermediates that may be related to ongoing neurotransmission.
