Examples of T1 and T2 in biological tissues include:CSF, T1=1.9 seconds and T2=0.25 seconds; brain white matter, T1=0.5 seconds and T2=0.07 seconds (70 msec). 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. It can cause issues with memory, balance and mobility. Analytical cookies are used to understand how visitors interact with the website.
