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. The dipole-dipole interaction is also increased the strength of the local field which is dependent on the proximity of the adjacent dipoles.

I noticed on my MRI results that it said There is a single punctate focus of T2 prolongation in the left corona radiata, nonspecific. As motion, and therefore the local field fluctuations, decreases below the Larmor frequency in tissues and tendons,dipoles that are aligned with the main magnetic field start contributing to T2 relaxation by causing local variations in precession rate. a focus of T2 hyperINTENSITY means that the signal from that area has different tissue characteristics compared to normal brian tissue.

[12], It is also thought that WMH have a negative impact on cognition in people with Alzheimer's disease. What causes increased signal in the normal supraspinatus tendon? A short T2 means that the signal decays very rapidly. For example, a brainstem lesion can cause room spinning sensations and balance problems. One that immediately comes to mind (suggested by my colleague Graeme Bydder) is the Pulsed Pathological tissue usually has more water than normal brain so this is a good type to scan to pick this up. Neurologist isn't worried. Kinesiology Tape (KT Tape) or Shoulder Sling. What is the grading scale for supraspinatus tendinopathy? T2 weighting tends to require long TE and TR times.
