A T2WI relies upon the transverse relaxation (also known as "spin-spin" relaxation) of the net magnetization vector (NMV). a focus of T2 hyperINTENSITY means that the signal from that area has different tissue characteristics compared to normal brian tissue. The spots (called lesions) on the scan are areas of active inflammation. This condition can increase a person's risk of experiencing abnormal heart rhythms and . To the right are images of a brain tumor with intrinsically long T1 and T2 values having opposite intensities on T1- and T2-weighted images. Cervical (neck) spinal cord T2/FLAIR lesions could cause tingling and numbness in the hands and legs. My Dad has metastic NSC Lung cancer. "Nonspecific" usually means cause unclear/many possible causes and often implies "low concern".

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. Alteration in muscle T2, notably T2 prolongation due to increased intracellular or extracellular free water (muscle edema), is best detected with inversion-recovery and fat-suppressed T2-weighted images (, 1,, 2 ). Carroll T, Smith CD, Liu X, Bonaventura B, Mann N, Liu J, Ebraheim NA. Spinal Cord. The volume and frequency is strongly associated with increasing age.

One that immediately comes to mind (suggested by my colleague Graeme Bydder) is the Pulsed Foci of increased T2 signal intensity were found on brain MR scans in 16 (59%) of 27 healthy elderly volunteer subjects, ages 63 to 86 years old. We report the radiologic-histopathologic concordance between T2/FLAIR WMHs and neuropathologically confirmed demyelination in the periventricular, perivascular . Accessibility In all tissues, there exist tiny magnetic fields (~1mT) generated by the spinning hydrogen nuclei (protons). In solutions of macromolecules and tissues the relaxation rate is much faster, i.e., the T2 time is shorter. after an RF excitation pulse, there is relaxation of the spins from the transverse plane toward the main longitudinal magnetic vector (B 0) - this is T1 weighting.

It is not intended to be and should not be interpreted as medical advice or a diagnosis of any health or fitness problem, condition or disease; or a recommendation for a specific test, doctor, care provider, procedure, treatment plan, product, or course of action. 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). Following a radiofrequency pulse, this form of relaxation occurs with the time constant T2, where T2 is the time it takes for the transverse magnetization vector to decay to 1/e or 37% of its initial magnitude.

That is the case with my hubby. Characterization of the abnormal areas of T2 signal as well as their appearance on other MR imaging sequences, when combined with clinical context and laboratory investigations, will often allow a unique diagnosis, or at least aid in narrowing the differential diagnosis. Deep white matter hyperintensites occur deep within white matter, periventricular white matter hyperintensities occur adjacent to the lateral ventricles and subcortical hyperintensities occur in the basal ganglia. A mri was taken and the impression says abnormal t2 prolongation identified in the periventricular white matter region, what does this mean?
