WebIn the Responders group, DWI T2 shine-through effect was present during MRI follow-up and in particular in 53 of 77 patients in the 6 months of follow-up (P < 0.05). Moreover, in the same group was present a statistically significant discs' shrinkage in the sixth month of follow-up (P < 0.05) as showed by IDVA. WebHowever, because DWI sequences contain T2 weighting, areas within the brain with high inherent T2 signal intensity can also show increased signal on DWI sequence, so-called T2 shine-through. To distinguish T2 shine-through from true restricted diffusion, consult the apparent diffusion coefficient (ADC) map. Areas of T2 shine-through will be ...
