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.

Mri (Definition)

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

Can MRI of brain see aneurysm or blood vessel problems (vasculitis)?

Can MRI of brain see aneurysm or blood vessel problems (vasculitis)?

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.

Magnetic imaging: MRI is a way to see what is happening with in the brain. The machine use magnetic waves to generate the information that is displayed on a computer screen. This is different than CT which uses X-rays to get the image

When a brain MRI is necessary?

See long answer: Your dr. Needs to exam you, and place the need for imaging, such as a “brain mri” in appropriate clinical context.

I'm going for my first brain mri, what are things I should ask?

I'm going for my first brain mri, what are things I should ask?

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.

What causes bright spots in 1 year old brain mri?

What causes bright spots in 1 year old brain mri?

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.

Hello docs, is a brain MRI common for headache sufferers?

Hello docs, is a brain MRI common for headache sufferers?

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.

Does hippocampus damage from hypoxia show up on a standard brain MRI?

Does hippocampus damage from hypoxia show up on a standard brain MRI?

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.

Can a brain MRI detect nonspecific supratentorial white matter disease?

Can a brain MRI detect nonspecific supratentorial white matter disease?

Yes: Nonspecific white matter disease may be seen in individuals with migraine headache, can be post infectious or can be a result of hypertension and high cholesterol. At times MRI with administration of contrast is recommended to better characterize these lesions.

What does it mean if a t2 prolongation on brain mri is getting larger?

What does it mean if a t2 prolongation on brain mri is getting larger?

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.

Can your mri of the spine be negative for MS, but your brain mri postive?

Can your mri of the spine be negative for MS, but your brain mri postive?

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.

Re: brain MRI - what is the difference between a lesion and an infarction?

Re: brain MRI - what is the difference between a lesion and an infarction?

Stroke vs tumor: Infarction is affected area due to lack of blood supply. Lesion can be due to a cancerous or non-cancerous tumor or infection or old scar or even or area affected by a store in the past.

What does parietal periventricular signal alteration on a brain MRI mean?

What does parietal periventricular signal alteration on a brain MRI mean?

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.
