Acquisition parameters for the sequences included in the MRI protocol

MRI sequence	Acquisition parameters
Sagittal 3-dimensional (3D) T1-weighted magnetization prepared rapid acquisition gradient-echo	Repetition time = 8.1 ms, echo time = 3.7 ms, matrix size = 240 × 222, field of view = 240 × 240 mm2
Sagittal 3D T2-weighted fluid attenuated inversion recovery	Repetition time = 4800 ms, echo time = 289 ms, inversion time = 1000 ms, matrix size = 224 × 224, field of view = 250 × 250 mm2
Axial 2D T2*-weighted, single-shot, echo planar imaging	Repetition time = 2600 ms, echo time = 35 ms, time points = 200, matrix size = 96 × 94, field of view = 230 × 230 mm2. Prior to the acquisition of this dataset, patients were instructed to close their eyes and rest without falling asleep.
