WebDec 26, 2024 · Spots on a brain MRI are caused by changes in the water content and fluid movement in the brain tissue. These changes happen when the brain cells are inflamed or damaged. These spots (lesions) are easier to see on T2 weighted images —a medical term that refers to the frequency (speed) of the radio impulses that are used during the scan.

WebJan 1, 2024 · SUMMARY: Abnormally decreased T2/T2 FLAIR signal can be seen on brain imaging of patients who are experiencing clinical or subclinical seizures and can be associated with various intracranial pathologies. We identified 29 such patients. The abnormal signal was unilateral in 75.9% of patients. 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. These small regions of high intensity are observed on T2 weighted MRI images (typically created using 3D FLAIR) within cerebral white matter (white matter les…
