Unit 3: Neuroimaging Techniques Flashcards
Works by sticking small metal discs called electrodes onto your scalp, measure brain waves, electrical activity
Electroencephalogram (EEG)
Used in sleep studies, detect abnormalities in your brain waves
EEG
Use a dewar machine that has multiple sensor coils within it, does not touch patient’s head, but goes around it, creates bigger picture of brain through magnetic field
Magnetoencephalography (MEG)
Might help pinpoint the source of seizures; shows where abnormal electrical activity is happening in the brain
MEG
Slice of x-rays of the head that generate images that may locate brain damage
Computed Tomography (CT)
These scans are performed to. help diagnose tumors, investigate internal bleeding, injuries, or damage. Helpful in detecting brain damage
CT Scan
Uses tracer (radioactive drug) that is injected into vein; an imaging test, photographs activity because of the glucose area in brain
Positron Emission Tomography (PET)
Tracer will appear and collect in seas of the body that have higher levels of metabolic or biochemical activity, pinpointing area of disease. Alzheimer’s and dementia patients may use this.
PET
Powerful magnets which create a strong magnetic field that causes atoms in the body to spin and align in the same direction, shows soft tissue
Magnetic Resonance Imaging (MRI)
Diagnoses conditions that affect the soft tissue, such as the brain. Used to detect brain tumors, traumatic brain injury, and other brain issues or diseases.
MRI
Uses a scanner with a powerful magnetic field to detect brain activity. Shows soft tissue, with area of your brain that are active.
Functional Magnetic Resonance Imaging (fMRI)
Creates a color-coded map of your brain activity, It can study cognitive processes and how disorders affect brain function.
