  1. The reference T2 was acquired with multi-echo spin echo, the reference T1 with inversion recovery. The measured T2 and T1 is based on the T2- and T1-mapping as described for the in-vivo-measurements. The estimate of the SNR stems from the first image of the T2-series and the last of the T1-series
