MR Spectroscopy - Anyone have one??

hi there has anyone had one of these tests?  Just wonder how common and why I'm waiting for one...I know they look at the lesions... but wonder how common this procedure is and if it can help with getting answers?

Also, my left leg is getting very Stubborn... when it doesn't want to go...it won't ... even when I want it too move.. it will feel like it's not my leg...and just not move... that happened to me more then once... difficult to move or walk even with a walker when you leg just stops doing anything...

Does anyone get that too??  

any replies would be helpful ... thanks alot

I've never known anyone to have one, but that doesn't mean much.

Hi Andie,

I don't know a lot about this test either, sorry.

I'm sorry about the leg bit.  Mine have been stuck in cement all week.  

I understand.

Here's to your dx coming this year buddy.

Magnetic resonance spectroscopy (MRS) is different from MRI because MRS uses a continuous band of radio wave frequencies to excite hydrogen atoms in a variety of chemical compounds other than water. These compounds absorb and emit radio energy at characteristic frequencies, or spectra, which can be used to identify them. Generally, a color image is created by assigning a color to each distinctive spectral emission. This comprises the "spectroscopy" part of MRS. MRS is still experimental and is available in only a few research centers.

Doctors primarily use MRS to study the brain and disorders, like epilepsy, Alzheimer's disease, brain tumors, and the effects of drugs on brain growth and metabolism. The technique is also useful in evaluating metabolic disorders of the muscles and nervous system.

Magnetic resonance angiography (MRA) is another variation on standard MRI. MRA, like other types of angiography, looks specifically at fluid flow within the blood (vascular) system, but does so without the injection of dyes or radioactive tracers. Standard MRI cannot make a good picture of flowing blood, but MRA uses specific radio pulse sequences to capture usable signals. The technique is generally used in combination with MRI to obtain images that show both vascular structure and flow within the brain and head in cases of stroke, or when a blood clot or aneurysm is suspected.

Regardless of the exact type of MRI planned, or area of the body targeted, the procedure involved is basically the same and occurs in a special MRI suite

Okay I am having a dumb moment.  I had one of these.  I have here on disc.  Basically it shows the vessel structure.  They did mine to rule out stroke.

Hi

I had an MRA done after eposodes of passing out.  One time unconcious for a few

seconds.  The impression that the docs wrote on the bottom of my report was

MRA of the circle of willis is unremarlable.  No aneurysm,dissection or hemodynamically

significant stenosis is noted. Diffusion weighted images reveal no evidence of acute infarction.  I also have ms.   My neuro ordered the test.  Hope this helps  Linda

thank you for your replies and the information links etc..... so I gather the MRS isn't that common but is used to look at them further and get a better look at the lesions I guess.....

Well, lets hope that when I get it??  still waiting for the call... I contacted the MS clinic last week and they said I should get a phone call from the hospital that does these in a few weeks???  

I hope this tests will explain further to the Dr what is going on and I get some answers... I will let everyone know when I get a date for this test.. thanks for being here friends... it helps alot

take care

Hi, I'm sorry about the stubborn leg.  I haven't experienced that, really, just my legs not wanting to move because of lower back, hip, or pelvic pain making things stiffen up.  

It must be even more frustrating to just not be able to get the message through to get that leg a-moving.  I hope your leg starts listening to you again soon....

Your MRS sounds very interesting.  I hope they schedule it soon, and it helps point to some answers.  I think it's about time for some, don't you?
