Avanto tim 1.5t mri scanner

Images were acquired on a Siemens Magnetom Avanto Tim 1.5T MRI scanner (Erlangen, Germany). The protocol included a T1-weighted 3-dimensional magnetization-prepared rapid gradient-echo image (repetition time [TR] 2,250 milliseconds, echo time [TE] 2.95 milliseconds, inversion time [TI] 850 milliseconds, flip angle 15°, voxel size 1.0 mm isotropic), a fluid-attenuated inversion recovery (FLAIR) sequence (TR 14,240 milliseconds, TE 89 milliseconds, TI 2,200 milliseconds, voxel size 1.2 × 1.0 × 2.5 mm, interslice gap 0.5 mm), and a diffusion-weighted echo-planar imaging (EPI) sequence (TR 10,200 milliseconds, TE 95 milliseconds, voxel size 2.5 mm isotropic; 7 scans with b = 0 s/mm², 61 scans with b = 900 s/mm²).

Imaging data was acquired on a Siemens Magnetom Avanto Tim 1.5 T MRI scanner (Erlangen, Germany). The protocol included a three-dimensional T1-weighted magnetization-prepared rapid gradient-echo (MPRAGE) sequence (repetition time (TR) = 2250 ms, echo time (TE) = 2.95 ms, inversion time (TI) = 850 ms, flip angle = 15°, voxel size = 1.0 mm isotropic), a fluid-attenuated inversion recovery (FLAIR) sequence (TR/TE/TI = 14240/89/2200 ms, voxel size = 1.2 × 1.0 × 2.5 mm, interslice gap = 0.5 mm), a diffusion-weighted imaging (DWI) sequence (TR/TE = 10200/95 ms, voxel size = 2.5 mm isotropic; 7 scans with b = 0 s/mm², 61 scans with b = 900 s/mm²), and an eyes-closed resting-state T2*-weighted gradient-echo sequence (TR = 2400 ms, TE = 40 ms, voxel size = 3.5 × 3.5 × 4.0 mm, flip angle = 90°, fat saturated, interleaved ascending acquisition).
