(A) WM nulling TI values as a function of TS for different TFE factors: TFE=165 (dashed), TFE=244 (solid), TR=4.1 ms, α=8°; (B) different readout flip angles: α=8° (solid), α=4° (dashed), TFE=165, TR=4.1 ms; and (C) different TRs: TR=4.1 ms (dashed), TR=8.2 ms (solid), TFE=165, α=8°. In (D), (E) and (F), the computed GM (black) and cortical lesion signals (gray) for the condition in (A) through (C) are shown.
