T2 reflects the length of time it takes for the MR signal to decay in the transverse plane. The pattern of T1 lesions with contrast changes from month to month. FOIA 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. 2000 Nov;10(4):689-704 ,viii. . Subacute combined degeneration of the spinal cord (SCD). It goes on to say otherwise unremarkable. T2 relaxation occurs in a varying local magnetic field when there is transfer of energy between dipoles facing parallel and antiparallel to the external magnetic field, flipping each other in opposite directions. T2 refers to the time it takes to spin the hydrogen atoms. 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.

While the overall length of stay in the hospital was similar between patients with and without an increase in the T2 signal intensity (12.5 vs 10.3 days, respectively, p = 0.22), patients with an increased T2 signal intensity spent significantly more time in the ICU, and there was a strong trend toward an increased length of dependence on . Differential diagnosis of T2 hyperintense spinal cord lesions: part B Hyperintense spinal cord signal on T2-weighted images is seen in a wide-ranging variety of spinal cord processes. but no futher study has taken place. T2 refers to the time it takes to spin the hydrogen atoms. Supraspinatus tendinopathy can be graded using a modified 4-point scale from 0 to 3 based on previous studies.
