This finding has been variously attributed to the presence of fat, muscle, connective tissue, abnormal vascularity, or degenerative changes. 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 (M xy).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 . So substances with short T2's have smaller signals and appear darker than substances with longer T2 values. Please help keep this site free for everyone in the world!

Hyperintense spinal cord signal on T2-weighted images is seen in a wide-ranging variety of spinal cord processes. [8], In most elderly people, presence of severe WMH and medial temporal lobe atrophy (MTA) was linked with an increase in frequency of mild cognitive deficits. A T2WI relies upon the transverse relaxation (also known as "spin-spin" relaxation) of the net magnetization vector (NMV). I have a had a kidney cyst since 2009. Background White matter hyperintensities (WMH) lesions on T2/FLAIR brain MRI are frequently seen in healthy elderly people.

Characterization of the abnormal areas of T2 signal as well as their appearance on other MR imaging sequences, when combined with clinical context and laboratory investigations, will often allow a unique diagnosis, or at least aid in narrowing the differential diagnosis. T2 reflects the length of time it takes for the MR signal to decay in the transverse plane. This rate of flipping or transfer of energy between spins or dipoles increases as the frequency of the variation of the local magnetic field approaches the Larmor frequency.
