Diagnostic Approach to Intrinsic Abnormality of Spinal Cord Signal In an MRI report, the white spots might be described as: "High signal intensity areas". 1 What is increased T2 signal on MRI report? [10][11] Pathological signs of oligodendritic apoptosis and damage to axonal projections have been evident. National Library of Medicine 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 (Mxy). Usually this is due to an increased water content of the tissue. Punctate focus of t2 prolongation in the left centrum semiovale, What does it mean there is focal abnormal t2 and t1 prolongation.
