T2 relaxation | Radiology Reference Article | Radiopaedia.org 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. The resulting short T2 time causes tendons and other semi-solid tissues to appear dark on T2-weighted images. 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.

T2 relaxation, also known as spin-spin relaxation or transverse relaxation, refers to the progressive dephasing of spinning dipoles resulting in decay in the magnetization in the transverse plane (Mxy). after doing so it was noted on the report that a t2 hyperintensity had been observed on my left kidney . Hyperintensities are commonly divided into 3 types depending on the region of the brain where they are found. Intramedullary cord hyperintensity at T2-weighted MRI is a common imaging feature of disease in the spinal cord, but it is nonspecific.
