Signal foci is a white matter in the cerebrum. It is a common incidental finding on MRI of the brain of patients with a variety of diseases.
my husband has t2 intense foci in the subcortical white matter in the frontal and parietal reigon these are compatible with foci of chronic ischaemic change the finding is related to small vessel disease his mood swings are getting worse would this disease be a part of mood swings.
Ishcaemic foci are also called lacunar infarcts. They are caused when blood flow is interrupted to small areas of the brain. It can be detected by an MRI scan.
Hypointense foci refer to areas on a medical imaging study, such as MRI or CT, that appear darker than surrounding tissue due to reduced signal intensity. These foci may indicate the presence of abnormalities such as lesions, tumors, or areas of decreased blood flow. Further evaluation is often needed to determine the underlying cause and potential implications of hypointense foci.
what does the white matter mean? How serious of a surgery is it to remove the white matter?
The above includes what was the first line written under "impressions" on my radiology report related to an MRI done w/o and with Contrast which I was given recently. I'm going to see my neurologist today, but can tell you what I know now. The doctors I've spoken with so far expressed concern, then some calming words such as, "the report wasn't conclusive," as the radiologist had included a number of possible reasons for the results. However, I've since read the fact I had an MRI six years ago during which this foci was not present, this presents a problem. The fact the foci is in the periventricular area typically suggests a diagnosis of Multiple Sclerosis. However, my neurologist ask to look at the films himself, to confirm this foci or lesion, is new. If it is indeed a new lesion, this signifies a diagnosis of either Multiple Sclerosis or another demyelinating disease. (Note: I had a "small foci" of "abnormal T2 Flair" rather than being scattered. )
Punctate foci are 'lesions' on the brain, typically caused by unknown trauma to the brain or conditions where demyelination of brain tissue occurs. Punctate foci are identified by brain MRI, with and without contrast although using contrast normally provides a more accurate picture of all lesions. In layman's terms, punctate foci have also been described as 'popcorn calcifications' in the brain tissue. Some punctate foci are associated with normal aging process.
MRI
Foci in Spanish is FOCO
my MRI of my brain says there is dark fluid what does this mean
