Yes, T2 and FLAIR signal hyperintensities are typically associated with white matter abnormalities in the brain. These hyperintensities can be seen in various conditions such as aging, vascular changes, inflammation, or demyelination. They can be important markers for diagnosing and monitoring neurological conditions.
Supratentorial white matter disease refers to abnormalities or damage affecting the white matter in the cerebrum (the largest part of the brain located above the tentorium cerebelli). This condition can lead to various neurological symptoms depending on the extent and location of the damage, such as difficulties with cognition, motor function, or sensory processing.
Finding multiple hyperintensities in the deep white matter and occipital region bilaterally may suggest underlying neurological conditions, such as multiple sclerosis, small vessel disease, or other demyelinating disorders. These hyperintensities can indicate areas of inflammation, ischemia, or other forms of tissue damage. Further evaluation, including clinical correlation and possibly additional imaging or tests, would be necessary to determine the specific cause and significance of these findings.
What treatment to be given in this case
what does this mean? Impression: There are scattered foci of T2/FLAIR hyperintensity within the periventricular, deep and subcortical white matter. The findings are nonspecific but may be seen in mild to moderate small vessel ischemic changes. No evidence for acute infarct or hemorrhage.
Light can pass through matter that is transparent, but still be scattered if the matter is not completely uniform or smooth. Examples include frosted glass, wax paper, and frosted plastics.
It can be: -absorbed -reflected -refracted (scattered)
Dark matter is matter that is inferred to exist from gravitational effects on visible matter and background radiation, but is undetectable by emitted or scattered electromagnetic radiation.
Transparent?
T2 prolongation in supratentorial white matter refers to an abnormal increase in T2-weighted magnetic resonance imaging (MRI) signal in the white matter regions of the brain located above the tentorium cerebelli. This finding can indicate various underlying conditions, such as demyelination, edema, ischemia, or chronic microvascular changes often associated with small vessel disease. T2 prolongation suggests that there is increased water content or changes in tissue structure, which can be indicative of pathology. It is essential for clinicians to correlate these MRI findings with clinical symptoms and other imaging results for accurate diagnosis and management.
It's not a matter of duration, but a probability of occurrence. Isolated means about a 20% chance, while scattered, I believe, includes probabilities up to 50%.
it is made out of small molecules. Solid had molecules packed like sardines, liquid had the molecules been scattered abit, while gas molecules is scattered alot around.
