Anyways, you can totally see unfused vertebrae on an MRI but a CT is way easier. Your MRA should be neat.
Moreover, the contrast allows the doctors to observe functional abnormalities that are not visible on a regular scan like how well blood flowing through your vessels. Gadolinium is used as the contrast, and you must intimate the doctor or technician about any previous allergies to the contrast or previously compromised renal function. Hope this helps.
However, you have had a CT, and that is also used a great deal for tumors so unless it was tiny - your tumor was likely picked up.
There are nerve palsies that effect the face such as Bells Palsy and the like - but I would seek out a neurologist that treats nerve disorders and get EMGs and all to make sure that is not the issue as well.
Things that effect the nerves do not show up on any imaging.
I get a stinging pain on top of my head on right hand side about tree inches from my forhead. It feels like a blister under the skin. I have had an MRI scan and have a small Mengioma but that is on the other side. There was nothing to explain the stinging. I read elsewhere on this site that Clanzpine 2.5 ml should work for it but it didn't say what the complaint was. Any idea?
I hope that someone else can provide you more info. I have spent time trying to research it on-line, but didn't find out much except that there appears to be different kinds and causes of it. BTW, it is spelled "hemorrhagic migraine". You might spend more time to find out more about it on-line, but the very best thing to do is to get more information about it from your doctor who will know about your particular case.
It feels like a large pressure inside my head, and people have describe that my face changes from bright red to pale white every few seconds when this occurs. When this happens, it lasts for usualy 1 to 2 hours. An MRI scan I had a while back, not sure how long exactly, showed that I had some sort of blood circulation problems, although I have no further understanding on what this was. I have pretty much no medical knowledge so this confuses me greatly. any help would be greatly appreciated.
Well after 4 long weeks of waiting for my MRI scan, i arrive at the MRI unit yesterday evening only to be told as im getting onto the scanner that my MRI has been requested without contrast. i did try to tell the radiographer that it should have been with contrast as it was to diagnose MS.
The radiographer told me that contrast didnt matter and that MS would show on the type of scan they were doing (i know this not strictly true).
Hi,
I do not think that you are overreacting as it is normal for a person to be concerned about lesions noticed on the MRI scan. Also, any change in the type of the headache should be investigated to find out the cause.
Although it is difficult to comment without looking at the MRI scan, I think that these could be white matter lesions (WMLs) which are seen more often in migraine patients but their association with migraine is not understood.
If you do get an MRI make sure you have it done with and without contrast, if not you just wasted a lot of time and money.... and DO NOT just go with what your doctor says. I have seen countless times when docs ASSUME that contrast will be used because it is the STANDARD practice when searching for an acoustic nueroma. Trouble is, the folks running the MRI machine do not know that.
My obgyn said if necessary i should get one, what good is a healthy baby without a healthy mom. I am just worried about the effects on the baby. I am 27 weeks, work full time, and have a 2 year old. I am just so conflicted with what to do, not sure i can last another 13 weeks with this kind of pain. Tylenol does not help.
I am now being referred to a specialist who will order either a PET scan or an MRI. I am 51 and quit smoking 20 years ago.I am trying to keep this in perspective but am struggling with my mind and imagining the worst. I am also wondering whether most/ some lesions are cancerous? Are there pre-existing factors that would cause the lesions to be cancerous? I have already posted this somewhere on this site before I found this specific area. Sorry about that. Any thoughts?
