Vasculitis Brain Mri
Brain MRI results: differential includes nonspecific demyelinating process such as MS vasculitis and infectious etilogies. What does this mean?
Meaning of MRI: Differential- this refers to the list of possible diagnoses for the person. The radiologist is not exactly sure what the imaging diagnosis is but what they are saying is that it looks like is ms or ms like things. Ms vasculitis (swelling of the arteries seen in ms). The other thing he/she thinks is possible are infectious etiologies (causes: such as bacterial or viral infection.See 2 more doctor answers
Mri or magnetic resonance imaging is one of the more recently developed imaging modalities available to physicians. It uses powerful magnets to generate images. There is no ionizing radiation which is a major advantage over many other modalities. Mri is the best imaging exam that we have for most soft tissue and joint related problems. There are radiologists ...Read more
MRI and MRA brain: Yes, an MRI can visualize blood vessels but not well; an MRA (MR angiogram) is the optimal MR test. It uses gadolinium which is not a radio-iodine and is not kidney toxic. Gadolinium can be eliminated slowly however, if a person has kidney impairment, and then the gadolinium can enter dermal tissues. Radiologists are aware.
See long answer: Your dr. Needs to exam you, and place the need for imaging, such as a “brain mri” in appropriate clinical context. There are detailed criteria that are used in making this determination. You can view them on the website for the american college of radiology appropriateness criteria: http://www. Acr.

First MRI: Ask if the machine is 'closed' or 'open'. If you have difficulty in close spaces ask for an open machine. Ask what types of things you can bring with you. Metal that can be magnetized is not allowed. Ask about dental braces or metal orthopedic metal. If you are very nervous, ask about sedation.
MRI: The best person to interpret your MRI is the ordering physician as he has all the history which you need to. To make a definitive diagnosis from a scan
Lots of things: "bright spots" on an MRI have various causes. They can range from benign, insignificant findings to infections, injuries, metabolic problems and more. An MRI is only a tool, and the findings need to be put in the context of the patient's clinical condition. Mri's are often ordered unnecessarily and then odd findings (like bright spots) can make a straightforward case much more confusing.See 1 more doctor answer
Not uncommon, but: In well over 98% of all migraine patients, the MRI is totally normal and reassuring. I tend to do very few images these days in my migraine patients unless the neurological exam shows some suspicious abnormality raising concerns. Perhaps your doctor has similar concerns, discuss with your doctor.See 1 more doctor answer

Sometimes: Damage to the hippocampus may show up on MRI, especially if it is the reason the MRI is done- so that the hippocampus is examined in detail. Keep in mind though that extensive damage is ordinarily needed to show up on the MRI, and small disruptions may not show up. So there can be a damage and a normal MRI, unfortunately.See 1 more doctor answer
Very complicated ans: Without going into the physics of MRI (which I doubt even the most ardent Radiologist could explain), prolongation of the T2 signal (a bright area on T2-weighted images) generally means a higher water content - swelling from stroke, inflammation, tumors, infections can cause this. If you've had multiple MRIs, increasing prolongation may not mean much as each MRI is obtained differently.
MY MRI's?: Well, thanks for asking. MY MRI's of the spine and brain...well, they're very well thank you. ;) But I guess we're talking about maybe YOUR MRI's? I need to say 1 very important thing. Listen up...MRI's don't diagnose MS. Qualified people do. An MRI of a spinal CORD can definitely NOT show signs CONSISTENT with MS while a brain's does. Make sense? Maybe? Got pictures? Ww.healthtap.

A change: There is a change in the signal in the tissue that surrounds the brain ventricles. That is not very specific. For example as we get older than say 20? then this finding may become more prominent. It also depends on why you had the study done in the first place. It may reflect why you are having symptoms. To put it all together talk to your doctor.
No: You can be fully clothed while having an MRI of your brain.
