Would an mri from the er looking for blood clot or bleeding find lesions?

Wgen I had a seizure and fell and had major concussion and confusion and head contusion, they did an mri this was a year ago, I had no symptoms.

Now I have symptoms that my doc thinks could possibly be ms, my question is do they have to be specifically looking for ms type lesions to find them, our would they show up on an er mri looking for other emergency related things?

It is possible.  You should get a copy of that MRI, if you can.  Since they were not looking for demyelinating disease, they may have ignored a few UBOs (unknown bright objects.)

So when I had my mri  a year ago,i didn't have any symptoms I prob didn't have any lesions or ms. but its possible that I could have them now?

And to answer the question, RIS (Radiological Isolated Syndrome) - sometimes called "silent" MS - is lesions that get discovered on an MRI or the brain or spine.  So there are cases where an MRI is performed for some other reason that can start the diagnostic process for MS.

MRIs are not the first choice in the ER to look for bleeding or clots in the brain.  The first line diagnostic is usually CT scan.  They are fast and simple.  MRI has complex sequences and the derived computer generated image is not anatomically referenced.  Anytime accuracy is required, like surgical films or radiation therapy planning, CT is used.  Since CT is a real image, everything is rendered anatomically correct.

Most hospitals have 1.5T or 3T MRI.  The .7T Open MRIs  and 1T  units are usually in the imaging centers.

I have no clue lol.  How would I find out?

What strength was the MRI at the ER?  Usually the tesla's so low that they're just looking at structural changes.
