Magnetom trio tim syngo 3 tesla system

The MRI protocol had been harmonized amongst the different PharmaCog project centers^{36 (link)}. Images were acquired using a Siemens Magnetom Trio Tim Syngo 3 Tesla system at the MRI Core Facility (IDIBAPS) of the Hospital Clinic of Barcelona, Barcelona, and with a Siemens Magnetom Verio 3 T at the Hôpital Timone in Marseille. All participants underwent fMRI acquisitions during the recognition memory task. Further, T1-weighted structural images were used for neuronavigation purposes (MRI parameters are detailed on SM).

All participants were scanned with a Siemens Magnetom Trio Tim Syngo 3 Tesla system at the MRI Core Facility (IDIBAPS) of the Hospital Clinic of Barcelona, Barcelona, Spain. In the succeeding, only the acquisitions used in this investigation, both for research purposes and clinical screening, are detailed. Three identical rs-fMRI datasets [T2*-weighted GE-EPI sequence; interleaved acquisition; repetition time (TR) = 2,700 ms; echo time (TE) = 30 ms; 40 slices per volume; slice thickness = 3.0 mm; interslice gap = 15%; voxel size = 3.0 x 3.0 x 3.0 mm; field of view (FOV) = 216 mm; 178 volumes] were acquired, one each experimental day. Furthermore, a hr-3D structural dataset [T1-weighted magnetization-prepared rapid gradient-echo (T1-weighted MPRAGE); sagittal plane acquisition; TR = 2,300 ms; TE = 2.98 ms, inversion time (IT) = 900 ms; slice thickness = 1.0 mm; voxel size = 1.0 x 1.0 x 1.0 mm; FOV = 256 mm; 240 slices] was acquired on experimental day 1. In addition, an axial FLAIR sequence (TR = 9,000 ms; TE = 96 ms; slice thickness = 3.0 mm; FOV = 240 mm; 40 slices) was obtained on experimental day 2 (see Figure 1).
