Verio syngo

Each participant underwent multimodal MRI utilizing the same 3 Tesla Siemens Verio Syngo scanner running version MR B17. Sequences administered included a T1- weighted MPRAGE, T2-weighted, fluid attenuated inversion recovery (FLAIR), susceptibility weighted imaging (SWI), diffusion tensor imaging (DTI), blood oxygenation level dependent (BOLD) resting state and task-related functional imaging, and chemical shift imaging (CSI) spectroscopy. For this report, only the volumetric T1- weighted sequence (1 mm³ isotropic voxels) acquired utilizing a 32-channel head coil was examined (sequence parameters: field of view (FOV) = 256 mm, repetition time (TR) = 2300 ms, echo time (TE) = 2.98 ms, flip angle = 9°, and a slice thickness = 1 mm). Scan time was approximately 9:50.

Multimodal neuroimaging assessments were collected on a single 3T Siemens Verio Syngo scanner with 32-channel head coil. MRI and cognitive assessments were collected concurrently (same week, mode=1 day). T1-weighted and DTI sequences were analyzed in the current study.
The T1-weighted sequence was acquired with the following parameters: field of view (FOV)=256 mm, repetition time (TR)=2300 ms, echo time (TE)=2.98 ms, flip angle=9°, and slice thickness=1 mm. The DTI sequence was collected using a clinical TBI protocol with the following acquisition parameters: 64 noncollinear directions, baseline acquisition sequences at b=0 s/mm with diffusion-weighting sequences at b=1000 s/mm, 1.8 x 1.8mm in-plane resolution with slice thickness of 4mm, TR=6300 ms, TE=96 ms, FOV=203 mm. T1-weighted data were available from 156 participants and DTI data were available from 144 participants.
