Mono-Exponential T2-Analysis of a Two-Pool System Does Echo-Spacing Matter?

It is generally well accepted that tissue exists of multiple relaxation components, such as for example the free water protons and myelin-bound water protons in brain tissue. However, the spin-echo based quantification of a single T2 on such tissues is commonly considered being the gold standard. Within such an approach, the echo-spacing is believed to be of influence on the obtained T2. By means of simulations, we have shown that the echo spacing in a spin-echo acquisition for T2-quantification does not matter when performing a mono-exponential analysis of a two-pool system.
