I am a thirty two year old femalesix feet tall and three hundred forty pounds. WMH's are also referred to as Leukoaraiosis and are often found in CT or MRI's of older patients. For example, a brainstem lesion can cause room spinning sensations and balance problems. You have brain structures that show up white on MRI in this area. Pathological tissue usually has more water than normal brain so this is a good type to scan to pick this up. 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. a focus of T2 hyperINTENSITY means that the signal from that area has different tissue characteristics compared to normal brian tissue. Singapore Med J. The same conclusions and observations would not necessarily apply in other situations, such as if the sequence were a phase-sensitive inversion recovery one, for example. Areas of new, active inflammation in the brain become white on T1 scans with contrast.

The pictures show both old and new inflammation. Intramedullary cord hyperintensity at T2-weighted MRI is a common imaging feature of disease in the spinal cord, but it is nonspecific. Whether these radiological lesions correspond to irreversible histological changes is still a matter of debate. In solutions of macromolecules and tissues the relaxation rate is much faster, i.e., the T2 time is shorter. Another possible cause of these white matter lesions could be Lyme disease. In all tissues, there exist tiny magnetic fields (~1mT) generated by the spinning hydrogen nuclei (protons).
