I recently had an MRI to rule out a pseudotumor cerebri. In pure water T2 is long, about 3-4 seconds because water molecules move considerably faster than the Larmor frequency. 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 . HHS Vulnerability Disclosure, Help The same conclusions and observations would not necessarily apply in other situations, such as if the sequence were a phase-sensitive inversion recovery one, for example. The result is that the Mxy component of the magnetic vector decreases exponentially as a function of the T2 time constant (Figure 1).

Also how common are such findings that are "nonspecific"? a focus of T2 hyperINTENSITY means that the signal from that area has different tissue characteristics compared to normal brian tissue. One of the major challenges associated with the T2 assessment according to the RANO criteria is the differentiation between T2-progress and other causes of T2 signal increase, such as edema, radiation effects, decreased corticosteroid dosing, seizures, postoperative changes, or even ischemic injury. It says multiple (greater than 25) small abnormal T2/flair signal throughout the periventricular deep and subcortical whitemat?
