White Matter And Grey Matter In Ct Brain

Nuclear studies have shown glucose metabolism equal to that of normally positioned gray. This research is yet to be integrated however and two fundamental questions remain.

Arteries and veins are well visualised as is the grey and white matter.

Due to great variation in imaging appearances these metastases present a common diagnostic challenge which can importantly affect the management approach for individual patients.
Gray matter heterotopia pl.
Heterotopias are neurological disorders caused by clumps of gray matter ectopic nodules of neurons located in the wrong part of the brain.




Subependymal grey matter heterotopia also known as periventricular heterotopia is the most common form of grey matter heterotopia and is characterized by nodules of grey matter located immediately beneath the ependyma of the lateral ventricles.
Eeg electroencephalogram monitors the brains electrical activity by means of wires attached to the patients scalp.
It would be unusual for a focal hyperintense focus in white matter to be a tumor.




These wires act like an antenna to record the brains electrical activity.
Dti has been shown to be sensitive to and to detect brain injury from diffuse axonal injury with more sensitivity than mri or ct.

Note that scans of the brain may be performed in any plane so slices can be made from any angle.
Since its introduction mri has become the imaging modality of choice for most body parts and the exquisite quality of images is best seen in the brain.




Numerous studies have begun to address how the brains gray and white matter may be shaped by meditation.
