Positron Emission Tomography

A medical imaging technique that uses radioactive tracers to visualize and measure changes in metabolic processes in the body.

Isotopes

Variants of a particular chemical element which differ in neutron number, and consequently in nucleon number.

Neurotransmitters

Chemical messengers that transmit signals across a chemical synapse, from one neuron (nerve cell) to another target neuron, muscle cell, or gland.

Final Answer :
D
Explanation :
Positron emission tomography (PET) does not produce a static image of the brain's anatomy, as do computed axial tomography (CAT) scans and magnetic resonance imaging (MRI). Instead, PET scans show the activity of different parts of the brain based on changes in blood flow and metabolism, making it a functional imaging technique rather than a structural one.
