Dr. Kennett is a neurologist who is conducting research using brain scans. He wants to study pictures of his subjects' brains while they are speaking or using a language. These pictures will help Dr. Kennett understand the parts of the brain that are being used to speak and the other processes that occur simultaneously in the brain. Based on the nature of study, it would be most suitable for Dr. Kennett to use _______.
A) functional magnetic resonance imaging
B) positron emission tomography
C) electroencephalography
D) computerized axial tomography
Functional Magnetic Resonance Imaging
An imaging technique that measures brain activity by detecting changes associated with blood flow, used to understand brain function.
Positron Emission Tomography
A nuclear medicine functional imaging technique that is used to observe metabolic processes in the body as an aid to the diagnosis of disease.
Brain Scans
Medical imaging techniques used to view the brain for diagnostic and research purposes, such as MRI or CT scans.
- Understand the role and value of diverse neuroimaging approaches in distinguishing between brain formations and abnormalities.

Final Answer :
A
Explanation :
fMRI is the most suitable imaging technique to study brain activity during language tasks such as speaking. It can measure changes in blood flow in the brain, which indicate which parts of the brain are being activated during speech. PET scans can also be used for this purpose, but they require the injection of radioactive tracers and are less precise than fMRI. EEG measures electrical activity in the brain, but it may not be able to localize brain activity as precisely as fMRI or PET. CAT scans provide only structural information about the brain and cannot measure brain activity.
