What should I be concerned for regarding very large simple kidney cyst? a focus of T2 hyperINTENSITY means that the signal from that area has different tissue characteristics compared to normal brian tissue. 1.6 x 0.7 cm and a dominant right-sided lesion in the parietal white matter approx. and transmitted securely. We report the radiologic-histopathologic concordance between T2/FLAIR WMHs and neuropathologically confirmed demyelination in the periventricular, perivascular . to serve as a baseline evaluation and staging the disease process. For potential or actual medical emergencies, immediately call 911 or your local emergency service. MRI is essential: to confirm the suspected diagnosis of MS. to evaluate for alternative diagnoses.

This dephasing effect has been likened to the opening of a Chinese fan. MeSH Cervical (neck) spinal cord T2/FLAIR lesions could cause tingling and numbness in the hands and legs. For these, please consult a doctor (virtually or in person). Does a "focus of T2 hypersensitivity" on an MRI always mean a lesion, or can it mean something else? T2/FLAIR lesions can directly account for some symptoms. At the time the article was last revised Patrick J Rock had no recorded disclosures. A T2WI relies upon the transverse relaxation (also known as "spin-spin" relaxation) of the net magnetization vector (NMV). Sufficient damage to the axons that course through WMH can cause adequate interference with normal neuronal functions. These small regions of high intensity are observed on T2 weighted MRI images (typically created using 3D FLAIR) within cerebral white matter (white matter lesions, white matter hyperintensities or WMH)[1][2] or subcortical gray matter (gray matter hyperintensities or GMH). 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. "Nonspecific" usually means cause unclear/many possible causes and often implies "low concern".
