Brain imaging

CT scan(cat scan) pros

3d X-RAY

Diagnostic of changes over time

Noninvasive and quick

CT scan(cat scan) clinical uses

See hemphorages( internal bleeding)

See tumor

See fractures and such

Damage to the meniges(increase contrast on picture)

DTI( diffusion tensor imaging) pros

See the movement of water in white matter

Helps see which parts of the brian are connected

noninvasive

DTI( diffusion tensor imaging) clinical uses

Helps see MS and tumors

Pre surgical planning

EEG(Electroencephalography) pros

Non invasive

See electrical acitivty of the regions of the brain by attaching electrodes to the head

Captures millisecond changes important for diagnosing

EEG(Electroencephalography) clinical uses

Diagnosing epilepsy and seizure disorders

Sleep disorders

PET scan pros

Help see if certain parts of the brain are functioning correctly(based on metabolic activity)

Sensitive to early changes in diseases

PET scan clinical uses

Diagnosing alzheimers(dementia)

Differentiate harmful and nonharmful tumors

Diagnosing cognitive decline

MRI

High detailed imagery of brian tissue allowing to easily see abnormalities

3d

Sensitive to changes

MRI clinical uses

Spotting tumors

Diagnosing MS

FMRI BOLD

Detect changes in blood oxygenation(BOLD)

BOLD(detects the decrease of deoxyhemoglobin,less oxygenated blood, as oxyhemoglobin floods the area)

Blood oxygenation level dependent

FMRI clincal uses

surgical planning and mapping brain area functions

EMGs(electromyograms)

• Recording of muscle electrical activity, used to diagnose neuromuscular disorders.
