Perfusion parameter results of the extended data analysis including all ${\text{T}}_2$-weighted scans after previous normalization to the mean signal of the conventional non-${\text{T}}_2$-weighted image per ${\text{TE}}_{\text{T2Prep}}$. Mean arterial transit time (ATT [s]) and cerebral blood flow (CBF [ml/100 g/min]) and statistical test–retest results (ICC, WSCV, SDD) in white (WM) and gray matter (GM).
