Measurements of the transverse relaxation time T-2 are usually conduct
ed with the Carr Purcell Meiboom Gill (CPMG) pulse sequence, which cau
ses T-2-weighted magnetization. Diffusion effects are a common source
of error in measurements of this kind, because the incoherent motion o
f spins in external magnetic field gradients distorts T-2 weighting of
the transverse magnetization. As a result, inaccurate T-2-values are
obtained. In this work, we present a method which completely compensat
es for the effect of diffusion.
