TECHNIQUES OF BRAIN IMAGING

What is a key benefit of utilizing an fMRI scan?

• Provides real-time monitoring of brain activity

• Offers detailed information on brain structure

• Can be used to study brain function in small animals

• Enables researchers to track brain responses during cognitive tasks

Which technique has the best temporal resolution for measuring brain activity?

• Computerized axial tomography (CAT)

• Functional magnetic resonance imaging (fMRI)

• Magnetic resonance imaging (MRI)

• Electroencephalography (EEG)

What is a limitation of EEG scans?

• Used to diagnose tumors and metastases

• Offers extremely low spatial resolution

• Measures neuronal activity directly

• Can be used for people with implanted medical devices

Which technique is good at measuring several second behaviors such as memory and face recognition?

• Computerized axial tomography (CAT)

• Positron emission tomography (PET)

• Electroencephalography (EEG)

• Functional magnetic resonance imaging (fMRI)

What is a strength of MRI scans?

• Does not use x-rays

• Has poor temporal resolution

• Can cause claustrophobia

• Used to diagnose epilepsy and sleep disorders

Which technique is used to observe metabolic processes in the brain by detecting gamma rays emitted indirectly by a tracer?

• Functional magnetic resonance imaging (fMRI)

• Magnetic resonance imaging (MRI)

• Positron emission tomography (PET)

• Computerized axial tomography (CAT)

What is a limitation of fMRI machines?

• Poor temporal resolution

• Can cause claustrophobia

• Used to measure instantaneous processes

• Excellent spatial resolution

Which technique is good at detecting tumors and metastases in the brain?

• Magnetic resonance imaging (MRI)

• Electroencephalography (EEG)

• Computerized axial tomography (CAT)

• Positron emission tomography (PET)

What is a strength of EEG scans?

• Low-cost technique

• Offers extremely low spatial resolution

• Measures activity of inner brain areas

• Used to establish the origin location in the brain

The patient will be given a radioactive substance and asked to complete a task to see which part of the brain is being utilized.

• MRI

• PET

• CT Scan

• EEG
