One that immediately comes to mind (suggested by my colleague Graeme Bydder) is the Pulsed Whether these radiological lesions correspond to irreversible histological changes is still a matter of debate. I noticed on my MRI results that it said There is a single punctate focus of T2 prolongation in the left corona radiata, nonspecific. Rest. [citation needed], Hyperintensities are often seen in auto immune diseases that have effects on the brain. What causes increased signal in the normal supraspinatus tendon? [5] Hyperintensities appear as "bright signals" (bright areas) on an MRI image and the term "bright signal" is occasionally used as a synonym for a hyperintensity.

The MS Lesion Checklist provides brief definitions for 10 types of lesions that are best appreciated on axial or sagittal T2-weighted (T2W) and fluid-attenuated inversion recovery (FLAIR) sequences. Causes including simple MR artefacts, trauma, primary and secondary tumours, radiation myelitis and diastematomyelia were discussed in Part A. 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.

My doctor wants me to have blood drawn, a urinalysis and an ultrasound. prolongation definition: 1. the act of making something last a longer time: 2. the act of making something last a longer. 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).
