What does it mean to have abnormal T2 flair signals?

Abnormal T2 FLAIR (Fluid-Attenuated Inversion Recovery) signals on MRI can indicate the presence of various pathological conditions in the brain, such as inflammation, edema, tumors, or demyelination. These signals often appear as hyperintense areas, suggesting changes in water content or tissue integrity. Conditions like multiple sclerosis, stroke, or infections could manifest with such findings, necessitating further clinical correlation and evaluation for accurate diagnosis and management.
