Can an EEG (electroencephalogram) detect brain tumors?

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

What does slow brain waves on an EEG mean?

What does slow brain waves on an EEG mean?

Not clear: It could be due to medications or brain injury or systemic poisons. If there is severe slowing, it could indicate deep coma with poor chances of recovery. ...Read more

What brain test can pick up brain tumors?

What brain test can pick up brain tumors?

CT OR MRI: A ct scan of the head or an MRI of the brain can pick up brain tumors. An MRI is a more sensitive test but takes longer to do. ...Read more

What brain problems does an EEG detect?

What brain problems does an EEG detect?

Many: Mostly eeg is used to diagnose epilepsy, it is also used to diagnose to diagnose brain death. It can be found abnormal in many focal or diffuse diseases, herpes simplex j. C disease. By eeg alone specific problems are not always diagnosable. ...Read more

Does poor r wave progressive and nonspecific st&t adnormal waves mean you had a heart attack. The findings were from a nuclear stress test.

Does poor r  wave progressive and nonspecific st&t adnormal waves mean you had a heart attack.  The findings were from a nuclear stress test.

Poor R wave: Poor r wave progression could be seen in old anterior myocardial infarction (old heart attack), in lead misplacement of precordial leads by inexperienced ekg technician, also can be seen pulmonary diseases, WPW syndrome, and dextrocardia. Dextrocardia is very rare. Wpw will be seen in much young age. If you have old heart attack you should see it in nuclear stress test. ...Read more

Is an upright P wave V1 and inverted P wave aVL with tachycardia indicative of ectopic rhythm? other ekg shows biphasic P wave V1, upright P wave aVL

Is an upright P wave V1 and inverted P wave aVL with tachycardia indicative of ectopic rhythm? other ekg shows biphasic P wave V1, upright P wave aVL

If the tachycardia: is occurring at rest with changes in the P wave morphology then it might be an ectopic atrial tachycardia. If it is occurring during exercise it is not diagnostic and may still be a normal sinus mechanism. ...Read more

What can a mra detect that a brain MRI cannot detect?

What can a mra detect that a brain MRI cannot detect?

MRA shows arteries: Mr angiography (mra) is an MRI which uses special sequences/techniques to highlight the arteries in the area scanned to look for abnormalities such as aneurysms. Like any test, it is not 100% accurate, but performed correctly and interpreted by a qualified radiologist, it is a great test to screen for arterial abnormalities. ...Read more

Could a mri/ct scan detect all brain injurys?

Could a mri/ct scan detect all brain injurys?

Nope: Sometimes you can see evedence of bleeding. With traumatic brain injury sufficient to cause changes on ct typically survival is markedly reduced. Certain types of MRI done at the right time following a brain injury can sometimes show evidence of cerebral contusion. Much of the damage done with traumatic brain injury is microscopic (too small even with diffuse axonal injury) to be seen on mri. ...Read more

Would a blood test show brain tumour?

Would a blood test show brain tumour?

Not likely : (unless it was doing something weird like pressing on your hypothalamus or secreting pituitary hormones). Brain tumors are suspected based on history and physical exam, confirmed with a head scan (MRI), and classified by a biopsy. ...Read more

Could brain MRI detect meniere?

You need 3T MRI: Look up 3t MRI and meniere's disease. I would also suggest a 32 channel MRI head coil. ...Read more

What does this mean? - BORDERLINE ECG - SINUS RHYTHM BORDERLINE R WAVE PROGRESSION, ANTERIOR LEADS BORDERLINE T ABNORMALITIES, INFERIOR LEADS

Finding not a diagno: Assuming ur EKG was collected correctly (i.e., the wires & patches were put on correctly), it's not entirely as expected for a person of your age & gender. You have sinus rhythm, but the spikes (R waves) do not progress between the wires as expected, & minor changes in the signals from the front (anterior) & bottom (inferior) part of the heart may be "just you" or signs of (prior?) damage. TTYD. ...Read more

St-t wave changes,consider inferolateral ischemia on ecg, echo shows heart good. Doctor said are few heart interruptions. What means? 27 yrs. Thanks

St-t wave changes,consider inferolateral ischemia on ecg, echo shows heart good. Doctor said are few heart interruptions. What means? 27 yrs. Thanks

ST-T wave changes: ST-T wave changes often are non-specific and may not mean anything. There are some ST-T changes that are the hallmark of heart attack, but I doubt this is your case as you echo was normal. Modern computerized ECG machines will always say "consider ... ischemia" with any ST-T wave abnormality. ...Read more

What does T2 Flair minimal periventricular hypertensive signal in brain MRI means?

What does T2 Flair minimal periventricular hypertensive signal in brain MRI means?

Usually nothing: There are many reasons for FLAIR periventricular hyperintensity. Usually, especially in older people, it means changes in the blood vessels in the brain. This is often due to a combination of atherosclerosis, demyelination (loss of the "white matter" covering the nerves), and scarring. It is very common and usually clinically insignificant. This is likely your case by use of the word "minimal." ...Read more

What test will show brainstem activity other than eeg.

What test will show brainstem activity other than eeg.

None: No test shows activity directly. Some tests can be used to assess certain functions of the brainstem. This includes vestibular testing, some forms of autonomic testing, eye movement testing, among others. ...Read more

What does parietal periventricular signal alteration on a brain MRI mean?

What does parietal periventricular signal alteration on a brain MRI mean?

A change: There is a change in the signal in the tissue that surrounds the brain ventricles. That is not very specific. For example as we get older than say 20? then this finding may become more prominent. It also depends on why you had the study done in the first place. It may reflect why you are having symptoms. To put it all together talk to your doctor. ...Read more
