Brain Scan

A patient is experiencing unusual bouts of memory loss and mood

swings. Doctors suspect that there might be abnormal activity in the

brain regions associated with these functions. To investigate, they inject

the patient with a radioactive tracer and observe the brain activity while

the patient performs memory and mood-related tasks.

• Pet Scan

• Lesions

• MRI

• FMRI

A patient arrives at the emergency room after a car accident,

complaining of severe headaches and dizziness. The doctors need to

quickly assess if there is any structural damage or bleeding in the brain.

They decide to use an imaging technique that provides detailed cross-

sectional images of the brain.

• PET SCAN

• CT Scan

• Lesions

• MRI

Researchers are studying the brain regions involved in decision-

making. They ask participants to perform a series of decision-making

tasks while lying inside a scanner that measures changes in blood flow to

different parts of the brain.

• PET Scan

• Lesions

• fMRI

• Mri

A neurologist is investigating the cause of a patient's frequent

seizures. They attach electrodes to the patient's scalp to measure and

record the electrical activity of the brain over a period of time, especially

during sleep.

• CT

• EEG

• MRI

• PET

In a controlled laboratory setting, researchers are studying the effects

of specific brain regions on behavior in animals. They surgically remove

or destroy targeted areas of the brain to observe changes in the animals'

behavior and understand the functions of those regions.

• PET

• CT

• Lesions

• MRI

A patient has been experiencing persistent, unexplained headaches.

Doctors want to get a detailed image of the brain's soft tissues to look

for tumors or abnormalities. They decide to use a non-invasive imaging

technique that uses strong magnetic fields and radio waves.

• MRI

• PET

• EEG

• Lesions

A sleep researcher is studying the different stages of sleep in

participants. They attach electrodes to the participants' scalps to

monitor and record the electrical activity of the brain throughout the

night.

• FMRI

• MRI

• EEG

• PET SCAN

Psychologists are investigating the neural mechanisms of empathy.

They have participants watch videos depicting various emotional

scenarios while in a scanner that tracks changes in blood flow to

different brain regions associated with emotional processing.

• LESIONS

• FMRI

• PET

• EEG

In a study on animal behavior, scientists are investigating the role of a

specific brain region in fear responses. They selectively destroy this brain

region in a group of rats and then observe the changes in their behavior

when exposed to stimuli that previously induced fear.

• EEG

• CT

• PET

• FMRI

An elderly patient has been showing signs of cognitive decline. To

check for signs of a stroke or other structural abnormalities in the brain,

doctors decide to use an imaging technique that can quickly provide a

detailed view of the brain's structure.

• MRI

• PET

• EEG
