T2 blackout effect

A.Prof Frank Gaillard et al.

T2 blackout effect is a diffusion weighted imaging phenomenon, representing the reverse of T2 shine through. The 'true' diffusion signal (as determined by ADC values) is reduced on DWI images (e.g. B=1000) by the presence of very low T2 signal (on B=0 images).
