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 . The MS Lesion Checklist provides brief definitions for 10 types of lesions that are best appreciated on axial or sagittal T2-weighted (T2W) and fluid-attenuated inversion recovery (FLAIR) sequences. "Nonspecific" usually means cause unclear/many possible causes and often implies "low concern". As motion, and therefore the local field fluctuations, decreases below the Larmor frequency in tissues and tendons,dipoles that are aligned with the main magnetic field start contributing to T2 relaxation by causing local variations in precession rate. Other uncategorized cookies are those that are being analyzed and have not been classified into a category as yet. The resulting short T2 time causes tendons and other semi-solid tissues to appear dark on T2-weighted images. An increase in T2 signal intensity is often associated with chronic compression of the spinal cord, and it is well established that chronic compression results in structural changes to the spinal cord. I was advised a T2 hyperintense structure on my left kidney was found on an MRI I had for back problems. Each magnetic dipole exists in a microenvironment unique to the tissue where it belongs. It could be a simple kidney cyst. but no futher study has taken place. government site. For these, please consult a doctor (virtually or in person). What does it mean? Simple kidney cysts are more common as people age. 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. (An excellent review article, significantly expanding the work of Elster and Yokoo et al., formulating imaging contrast in terms of tissue-property filters and clarifying many paradoxes and misunderstandings concerning the concept of "weighting".

Whether these radiological lesions correspond to irreversible histological changes is still a matter of debate. 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.
