What does T2 hyperintensity mean on an MRI?

What does T2 hyperintensity mean on an MRI?

A hyperintensity or T2 hyperintensity is an area of high intensity on types of magnetic resonance imaging (MRI) scans of the brain of a human or of another mammal that reflect lesions produced largely by demyelination and axonal loss.

What causes T2 hyperintensity?

Hyperintense spinal cord signal on T2-weighted images is seen in a wide-ranging variety of spinal cord processes. Causes including simple MR artefacts, trauma, primary and secondary tumours, radiation myelitis and diastematomyelia were discussed in Part A.

What is foci of subcortical white matter?

Subcortical white matter, often simply called white matter, is a region inside the brain that has a high concentration of nerve fibers. These fibers are coated with a protein called myelin, which assists in transmission of electrical impulses down the fibers.

What is a subcortical white matter change?

We also find that subcortical white matter has more prominent changes than white matter close to the central brain. The observed changes in the subcortical white matter may be indicative of a mild demyelination and a loss of myelinated axons, which may contribute to normal age-related functional decline.

What is periventricular subcortical white matter disease?

Periventricular white matter functions as a connecting unit between areas of grey matter within the brain. The presence of PVWM may be confirmed through brain imaging scans. When plaque builds up in PVWM, Alzheimer’s disease may result. Changes to PVWM are common during the aging process.

What is hypoattenuation in the right parietal white matter?

Hypoattenuation (Hypodense) lesions may be due to many reasons. It is seen in lesions due to ischemia (decreased blood supply),gliosis, some brain tumour etc. You have focal area of white matter hypoattenuation and irregularity in right parietal white matter means there is hypodense lesion in mentioned part of brain associated with irregularity.
