T2/FLAIR lesions can directly account for some symptoms. Many of the lesions may not be causing obvious symptoms. I was advised a T2 hyperintense structure on my left kidney was found on an MRI I had for back problems. a focus of T2 hyperINTENSITY means that the signal from that area has different tissue characteristics compared to normal brian tissue. I have been hospitalized 3 times with rhabdo with a CPK of 7715.

Do brain T2/FLAIR white matter hyperintensities correspond to myelin Hyperintense spinal cord signal on T2-weighted images is seen in a wide-ranging variety of spinal cord processes. The above discussion presumes we are dealing with a "standard" magnitude-reconstructed spin-echo image. Analytical cookies are used to understand how visitors interact with the website. The volume and frequency is strongly associated with increasing age. This is related in part to the slower motion of protons both in macromolecules as well as water molecules attracted to the surface of the macromolecule.

Singapore Med J. 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. [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. An estimated 25 percent of people 40 years of age and 50 percent of people 50 years of age have simple kidney cysts.
