All data were collected using a 3-T Philips Achieva MRI scanner (Philips Healthcare, Best, Netherlands). T1-weighted anatomical images were acquired with the following parameters: repetition time (TR) = 280 ms, echo time (TE) = 14 ms, flip angle = 60°, field of view (FOV) = 24 × 24 cm2, matrix = 256 × 256, and slice thickness = 4 mm.
