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 . Deep white matter hyperintensites occur deep within white matter, periventricular white matter hyperintensities occur adjacent to the lateral ventricles and subcortical hyperintensities occur in the basal ganglia.

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/FLAIR lesions can directly account for some symptoms. 1987;149 (4): 831-7. The spots (called lesions) on the scan are areas of active inflammation. Typical examples are shown in Figures 1-8. [2] They are also seen in a number of neurological disorders and psychiatric illnesses. These foci were not related to cognitive function or cerebrovascular risk factors; instead, they were highly correlated to age, being present in 11 of 11 subjects aged 75 years and over.

Each magnetic dipole exists in a microenvironment unique to the tissue where it belongs. after doing so it was noted on the report that a t2 hyperintensity had been observed on my left kidney . 1.6 x 0.7 cm and a dominant right-sided lesion in the parietal white matter approx. Carroll T, Smith CD, Liu X, Bonaventura B, Mann N, Liu J, Ebraheim NA. Alteration in muscle T2, notably T2 prolongation due to increased intracellular or extracellular free water (muscle edema), is best detected with inversion-recovery and fat-suppressed T2-weighted images (, 1,, 2 ). [3][4] WMH volume, calculated as a potential diagnostic measure, has been shown to correlate to certain cognitive factors. t2 prolongation - Symptoms, Treatments and Resources for t2 prolongation Unauthorized use of these marks is strictly prohibited.

Particular features of the focal lesions on MR images (number, size, location, presence or lack of edema, reaction to contrast medium, evolution in time), as well as accompanyi The pattern of T1 lesions with contrast changes from month to month. The water that is in bone, teeth, and calculi would mostly be bound as to collagen and would have a very short T2 time constant and appear dark. The hyperintense focus is a bright spot, likely caused by higher than expected water content. Would you kindly let me know what this means. A: When making the diagnosis of MS, brain and cervical spinal cord MRIs should be obtained in all cases unless specific contraindications.
