mri scan brain machine

A CT scan and MRI are pretty much the tests that will find a tumor- if you've had 3 scans that have been normal I would think everything is okay.

http://en.wikipedia.org/wiki/Magnetic_resonance_imaging The above link tells you pretty much everything you didn't want to know about MRIs. I had a brain MRI one time, I had to be sedated because I was afraid of it, they even have a little mirror in there so you can see out of it, sort of claustrophobic in the machine, and they had a microphone and radio in there so I could talk to the techs. When the machine started up, it was VERY loud, surprised me, kind of made a bumping racket.

My recent brain-spine MRI was just over an hour. The power of the unit is important. You can study the types on the net. Most hospitals claim state-of-the-art for all their equipment, leaving patients pretty much in the dark. Even well-known centers can be weak in some areas. If you aren't satisfied with your improvement, learn more and keep looking for better treatment.

Do not get it on an open MRI machine! These machines are not strong enough for catching most (and sometimes all) of MS lesions. My first MRI was considered bogus by my neurologist. No lesions showed up. The next MRI showed lesions-- even a large lesion missed on the open one. To answer your question, MS is a clinical diagnosis.

The vice versa is true for MRI. MRI can produce images in any plane but CT scan cannot. CT scan uses X-ray imaging whereas MRI uses radio waves and magnets. Radiation exposure is moderate in CT scan and there is no radiation exposure in MRI. Hope this helps. Please let me know if there is any thing else. Take care!

Just a few words of advice (some of you probably already know) if the doctor wants to schedule you for a c,t spine and brain scan with and without contrasts at one time. Don't try it. Split them up if possible. I was in that machine for a little over two hours. I had to get out. Finished the contrast the next day. What a terrible experience!

Your are more at risk if there are brain lesions that are seen in MS on your MRI scan of develop definite MS later. Here is a web site.. http://www.nationalmssociety.org/about-multiple-sclerosis/diagnosing-ms/cis/index.aspx Devic's Disease is similiar to MS but requires a different course of treatment.

My first brain scan showed a lot of small perventricular lesions and my two bigger ones were on the occipital lobe and frontal lobe so I don't think they could be causing these symptoms. I guess I am just wondering if I should expect anything to show or if my sx are just too transient that if there are any lesions on the c-spine that they won't be detectable. I do not know what strength the machine is but I doubt it is more than T1.5-T2. Thanks!

m looking over all of my old records and scan reports, and found the following statement on the report for an MRI of the brain I had a year ago, that I just don't understand... It was written in the begining of the 'Findings' section. "This is a slightly limited study secondary to the lack of capability for fat suppressed imaging on the post-contrast images which limits evaluation for subtle enhancement of the optic nerves.

I just had an MRI on my eye due to pain.It ended up being a minor sinus issue. There was also mention of an "Artifact" on a single slice of the MRI. They have suggested a full brain scan as a precautionary measure. My Doctor say this is common and there is absolutely nothing wrong with me (no tumour or cancer) and I have no need to worry. Should I be? Could it be a tumor even thought it was only on 1 slice?

Well, its been 6 months so its time for my new MRI tomorrow (full brain and spine). Doctor said again that based on clinical history (new symptom of crazy vertigo showed up this past month) it looks like MS but we need something substantial on this new MRI (last one had 2 small spots in pons after radiologist gave it a 2nd look). So I'm going back to same machine, same protocol so we shall see. Send positive thoughts for answers, or permission to move on from limbo land.

I have been to the ER twice and have seen a spinal orthopedic. At my last visit to the ER they ran an MRI brain scan with contrast imaging; the MRI and the bloodwork all came up normal. I don't feel normal- I feel like someone has placed a tourniquet on the oxygen supply to the left side of my body.

The gist of this is to make sure that you confirm the protocol for an MRI before the procedure is done. I saw a doctor yesterday and he ordered an MRI of the brain; I talked about wanting it done on a T3 machine, something new in our area (yeah!). Today I talked to the person in charge of gaining insurance approval and discussed with her the T3 scan. I got a call from the intake person at the facility and had the wherewithal to ask if the scan was using a T3 machine. Nope.

Hi Tara and welcome to the forum. I don't believe we have "met" yet. My MS was diagnosed on a closed 1.5 Telsa MRI machine. However, the strength of the machine isn't the only factor. The software used to obtain the MRI cuts is just as important. I am lucky enough to have most of my MRIs taken on a 1.5t but it has the best software in the area ,including the academic centers.

m claustrophobic and probably going to have an MRI, not looking forward to it but still I find it a better option compared to a CT scan. By the way, each the MRI and CT scan are somewhat different in their function/purpose, so take that into consideration too. Good luck to you!

MS is as unpredictable in symptoms and disease course as it is the placement and number of lesions it causes. Additionally, the way the MRI was done and the strength of the machine makes it somewhat tricky. The weird thing was that I had an open MRI done and it was too weak to show ANY lesions. When I had another MRI done on a 1.5T machine, I had probably around five show up (give or take). My latest scan had many additional ones show up-- like someone splattered paint in my brain.

My Doctor order an MRI scan on my head to check for a Pituitary Adenoma, but she told me to only go in when I was having headaches. I was having headaches all weekend but I feel better today, and probably wont be able to go in for a few days since I need to make an appointment first. Will it matter if I have a headache or not when I go in? If there is an adenoma, won't it show up regardless? I'm just trying to figure out why I should wait?

Well, they did the 2nd MRI, but look like they did brain with and without contrast on a 1.5 t machine at a facility that has Two 3T machines. They said since the baseline was a 1.5 T the followup should be a 1.5 T, Guess I'll wait to see what the Neuro-Rad has to say. Also look like they didn't bother with the C-Spine. Just a bit frustrated.

Can you please explain my MRI of the brain done with and without contrast please: On T2 weighted and FLAIR sequences, there are multiple subcentimeter round ovoid foci of high signal in the right frontal lobe periventricular white matter, in addition to several subcentimeter lesions in the periventricular and subcortical white matter in the left frontal lobe and the subcortical white matter in the posterior right frontal lobe.

Hi there, If you have had repeat MRI over an extended period of time on a T3 machine using MS Protocol and a lumbar puncture (MRI of your thoracic, cervical and brain the chances of it being MS would be diminished. MRI is pretty good at imaging the brain, but not so good at imaging the spinal cord. Usually a good neurologist can tell from examination and what symptoms you are having if your lesions are more likely to be spinal or brain.

As a result, an MRI examination can cost several thousands of dollars, as it includes a charge for using the MRI machine to perform the scan, as well as a professional charge for a radiologist to view the images. In the end, the MRI machine is a miracle, as long as you don't have a pacemaker, metal hip replacement or metal ANYTHING replacement, and you can afford it.
