I heard that they ask you questions during the EEG to see what happens to your brain in response to the questions...is this true?
Or do you just sit there?
What happens during the MRI? It's on my brain.

An MRI is a magnet resonance imaging- it is like a fancy CT scan but, it takes better pictures and is used to diagnose low blood flow areas of the brain, infarcts, or disease processes of the brain. EEG ELectroencephlagram- is used to detect brain waves and eletric impulses of the brain. This is used to diagnose seizure activity in the brain, or electric abnormalities of the brain.
They do not ask questions. The electrodes are placed on the head and they run a series of scans on you. Sometimes they will put a strobe light in front of you to detect seizures. The MRI is a big machine, if you are afraid of enclosed spaces let the tech know as the machine encompasses the head and is very noisy. They do provide ear plugs for you. You can hear the machine as it takes the pictures but you have to remain very still.
MRI is about 25-30 mins long, EEG is about 15-20 mins.

EEG is a study of your brain waves. For a Brain MRI, you will be asked questions in regards for clearance of any metal objects implanted on you (example if you might have a metal clip or a pace maker, then you can not have the MRI as it can be dangerous). Are you claustophobic? The scan usually lasts between 30 minutes to an hour. You might get injected with some contrast if your doctor ordered it to show some more details of your brain. Good luck in your exams.

Nobody asked me anything when I had my EEG, and MRI will require that you are lying still for a while so don't drink lots of coffee in the morning , wait til everything is over to get revved up. Nothing happens to you except to lie still in the machine.

It kind of feels like being in a coffin, but if you have a good tech doing it, they should stay in communication with you and help you stay relaxed. They are extremely loud. Make sure they give you ear plugs (you can still hear the tech talking). Sometimes they can play music, but the THUMP - THUMP - THUMP noise is pretty overwhelming. If you already have headaches, you might want to take some advil or something beforehand. Takes about an hour usually. It's usually cold in those rooms - wear clothes with no metal on them, but warm enough in a cool room. If you are claustrophobic, ask your doctor about getting a sedative first. Email me if you want more info/more specific questions.
