what is more accurate an MRI scan or the one with electrodes on the head ?

Answer 1

The 2 tests are looking for different things. The MRI is looking for physical brain abnormalities, bleeds, clots, injuries, tumours and malformations. The electroencephalograph, EEG, is looking for electrical disturbances, such as in epilepsy.

Answer 2

Depends on what the medical people are looking for and what your problem is. An MRI scanner will highlight any anomalies in the brain, such as clots,growths etc. whereas the electrodes (ECG) read the brain wave patterns to diagnose neuropathic problems.

Answer 3

The electroencephalograph (EEG) is used to detect brain waves, which the MRI cannot. The MRI gives a "picture of the interior of the body, which the EEG cannot.

It is not that one is more accurate than the other, they simply have different functions.

Answer 4

MRI is much more accurate its a 3D picture of your insides and the doctor can see so much more the electrodes can' t do that at all.

Answer 5

If you use these methods to diagnose something in your head, then they are complementary.

With MRI you will see the structures in the brain. With the electrodes (electroencephalogram =EEG) you have a recording of the brain activity.

Answer 6

I assume you are referring to an EEG when you talk about the one with electrodes on the head. These tests look for different things and are not comparable to each other.

Answer 7

MRI is a very sophisticated scan
the leads are usually used to monitor brain activity as in epilepsy
you may have epilepsy but for no apparent cause so if diagnosing epilepsy you will need both

Answer 8

They are two totally different things, it depends what your having these tests for.

Answer 9

MRI by far.
