[citation needed], Hyperintensities are often seen in auto immune diseases that have effects on the brain. 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.

How to detect T2 prolongation in skeletal muscle? 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. QT prolongation is the medical term for an extended interval between the heart contracting and relaxing. 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. A short T2 means that the signal decays very rapidly. and transmitted securely. In such cases the attending physician who ordered the study asks the radiologist who interpreted the study to elucidate further and determine whether Understanding radiology reports can be challenging.
