Can an EEG (electroencephalogram) detect brain tumors?

No: Eeg can show presence of seizure brain wave activity.These seizure brain activity can be caused by different conditions such as metabolic abnormality, lack of blood supply to brain cells, medication, epilepsy, brain tumor related, etc. It analyzes the brain "function" not the anatomy thus it can't detect brain tumor specifically. Mri needs to be done to detect brain tumors. Discuss with your md. ...Read more

Eeg (Definition)

An electroencephaolgram (eeg) is a test that uses wires on the scalp to measure electrical activity produced by the brain. It is used to assess cerebral activity, and can be very helpful in the diagnosis and treatment of seizures as well ...Read more

What doctor inteprets a EEG (electroencephalogram)?

What doctor inteprets a EEG (electroencephalogram)?

Neurologist: Diagnostic eegs are read by neurologists. Neurosurgeons are trained to read eegs as they relate to lesions to be removed during epilepsy surgery. ...Read more

Can MRI scan detect depression?

Can MRI scan detect depression?

Answer via Questions: We rely on the answers people give to questions about their thoughts, emotions and behaviors to determine whether (a) they have symptoms of depression; (b) how many they have; & (c) how severe each is/how much each interferes w/ person's ability 2 function day 2 day. Standard MRI machines produce great still shots of the brain but those pics don't show depression or what someone is thinking, etc. ...Read more

What is an electroencephalogram (eeg)?

EEG: An EEG is a test that records the various brain waves emitted from the brain. The test is done by placing tiny electrodes all around the head and scalp, and recording the electrical activity emitted by the brain and recorded by tracing the waves onto recording paper. ...Read more

Can an MRI scan show cognitive impairment?

Can an MRI scan show cognitive impairment?

NO: Mri is an imaging device that is independent of function. Think of your car mechanic and a problem with your car. Lifting the hood and looking is like getting an mri. A good mechanic will want to turn it on and drive around and think carefully about what may be wrong. A good brain mechanic will ask appropriate questions and get appropriate tests and think about what may be wrong. ...Read more

Will a spect scan pick up Generalized epilepsy?

Will a spect scan pick up Generalized epilepsy?

Might help: A 3-D SPECT scan is the poor man's equivalent of a PET, the former illustrating blood vessel flow patterns, and the latter, metabolic patterns. But we are dealing with anatomical variations secondary to a disorder, and with a paroxysmal process such as epilepsy, we are better off to use EEG monitoring to assess physiology. Can use ambulatory device over 24-48 hrs to seek conclusions. ...Read more

Would an EEG show MS? What about encephalopathy?

Not at all: EEG is not of value in confirming diagnosis of MS. If encephalopathy, abnormal EEG patterns may be present, but will not reveal etiology. Other tests needed to confirm either condition. ...Read more

Can an EEG detect tumors?

Not directly: Eeg measures the activity of brain cells, not tumors. If the tumor is effecting a significant number of brain cells, the eeg may be abnormal. Some tumors cause enough irritation of the brain to cause seizures. These seizures can be located in the brain by eeg. Some tumors will have no effect on the eeg. ...Read more

Ct scan, mri, nuclear medicine imaging, ivp scan, how are they different?

Ct scan, mri, nuclear medicine imaging, ivp scan, how are they different?

Quite different: Ct involves xray type radiation with cross sectional imaging in transaxial, sagittal, and coronal projections. Nuclear medicine, internal irradiation either injected intravenously, inhaled, ingested, injected subcutaneously.Ivp uses injection of contrast material for visualization of kidneys and bladder with x-ray. Mr imaging uses no ionizing radiation magnetic fields to generate x-sectional images. ...Read more

Could MRI or CT scan detect brain cancer?

Sure: Mri would be the imaging test of choice, though often we start with a ct. Ultimately, you'll likely need a biopsy to prove it's a cancer. ...Read more

Can a Pet scan diagnose Generalized seizures?

Can a Pet scan diagnose Generalized seizures?

Not really: Primary generalized seizures would not be expected to change anything on a PET scan. Partial-onset could show an area of altered metabolism. Either way, PET scans are not really a primary way to diagnose epilepsy. ...Read more

Could a brain MRI show a seizure?

Could a brain MRI show a seizure?

See below: An MRI of the brain can not show a seizure, per se, but can show damaged areas where seizures may originate from. An interictal meg, ictal spect, and pet scans can be of benefit in some cases. An eeg, which looks at "brain waves", can show certain seizures as well. But a good history and exam are key to diagnosing epilepsy. A neurologist can help you with this. Hope that helps! ...Read more
