To all MS experts: Can a Cat Scan show "signs" of MS?

I was just in the ER because I am having weird visual disturbances (although my eye exam was normal but I still get this weird shaky vision) and they ended up doing a Cat Scan which was totally negative so they said no tumors or bleeding on the brain.

However, I was wondering if MS will show up on the scan, even a trace of something wrong? I know the MRI is "the scan" for showing the lesions that indicate MS but even if the Cat Scan is not nearly as sensitive as the MRI, would it show something even vaguely on the Cat Scan if I had lesions due to MS?

Thanks!

A CT or CAT Scan will not, BUT if you are in early stages of symptoms it could get you to the right doctor. If your condition is not neurological, then the CT should be able to get you to the right doctor. If nothing shows up "wrong", then the CT, again, directs you to the right doctor.----- The aforementioned are my non-medical opinion ---

Re: To all MS experts: Can a Cat Scan show "signs" of MS?

Hi Mitch, probably not...but possibly. When I was first dx, they didnt know what was wrong with me and sent me in to a CT scan to rule out a pinched nerve.....the CT scan didnt show a pinched nerve, however it showed abnormalities.....those being marks on the CT which shouldnt have been there.

A neuro was called in to review the scans and immediately asked me to go for a MRI, where over 50 lesions were clearly identified. Fortunately for me, the Neuro was more familiar with what he was looking at, then the radiologist who read the CT scan. And, I got lucky....the oncall Neuro turned out to be a guy who is Head Neuro in the MRI center in my local hospital.

So, really it depends on WHO read the CT Scan and how familiar he or she was with what they were looking at.....were they looking for somthing in particular, didnt see it, and said its normal? Were they unable to see anything on the scan, so called it "clean" ? Was it done with and without contrast? Did they shoot the dye into your veins before the CT scan took place? The dye would have shown things that, without it, might not show up. Who actually recommended the CT scan and do you have a Neurologist whom you can discuss this with?

Most Opthamologists will agree, that a CT scan is NOT the test of choice for visual disturbances either...did they also do a visual Field Test? The one where you click on the clicker when you see the spots on the screen? This measures your peripheral vision...did they do an EMG or EEG? These are all tests that would routinely be done for a visual problem.

If you are answering no to any of these, you need to explore this further and with a good Neurologist or Optha-Neurologist....find out who is in your local area and get an appointment. On the other hand, if you had these tests and nothing was abnormal then you just want to watch it and see a Opthamologist regularly to make sure that your eye health is good....

Best of the best to you....
Nikki

Re: To all MS experts: Can a Cat Scan show "signs" of MS?

Thanks, guys. This information has been so helpful.

These weird, shaky, wobbly visual disturbances I have gotten for two weeks straight (along with a visual snow kind of thing) has me terrified to be honest. Along with that, I have cognitive problems. Sometimes I have to "think" to even remember my phone number!

I went to an ophthalmologist who could find nothing wrong with my eyes or optic nerve. He said entirely normal and thought this visual stuff was due to eye fatigue. I'm not buying it. I get migraines with aura and have my entire life. I feel like I am still in a mild "aura state" with the zigzag lines, wavy stuff, words wobbling, lots of "snow" in my visual field. It's so scary and annoying. I also have neck pain and have to wonder if this is connected. So today, I couldn't get in to see my regular internist because she was out of town for the holidays and they suggested I get to the ER to rule out severe, emergent issues which I guess they did with the cat scan. Tomorrow I am headed to the neurologist I see for migraines, only I cannot see him, but the nurse practitioner there because even he is out for the holidays.

So that is where I am sitting now. I have a fibromyalgia/myofascial pain diagnosis, migraines, I have stomach dysmotility (empties too fast and too slowly, figure that one out because I can't LOL) and that is what I have for a history... then these visual disturbances suddenly appear and have been a nightmare for two weeks now.

Thanks so much for helping me understand the cat scan versus mri.

I have MS and have shaky vision also. It's awful. It is called Oscillopcia. I also have double vision at times. You should get a MRI. A CAT scan did not show my lesions,
but the MRI did. from samandlibby

Hi, thanks for the post. I did get a full work up in the past week and they found nothing.

I had done:

MRI of brain - negative
MRA of brain - negative
MRA of neck - negative

A whole bunch of bloodwork - negative

============

I don't know what to do. My vision is a mess, shakes all the time. I cannot believe how messed up it is. The neurologist thinks my neck issues (spasm) are causing me to be in a chronic migraine aura state. So far the beta blocker is not working. I haven't started the physical therapy yet. The shaky vision is seriously the worst thing I have ever experienced in my entire life.

I will continue to keep you in my prayers. If it is MS, your MRI might need to be repeated in 6 months.

I know how stressful "not knowing" is. You are not alone in this feeling as most everyone with MS has experienced this to some degree.

Re: To all MS experts: Can a Cat Scan show "signs" of MS?

See a retinal specialist. I have the same problems and also have MS, but after 5 years with this and 3 visits to Neuro-ophthalmologist, as well as regular ophthalmologist, no answers other than it must be the MS from an previous optic neuritis flare up.
My last visit finally something caught the Dr's eye and he referred me to a Retinal Specialist. Never even knew they existed. With one look he was able to describe the distortion shape in my eye as well as reason for other problems. Right now surgery to correcct is optional, but if headaches continue I will go forward. The cause is simply "wrinkles" in my retina as well as a growth back there too.
