Images were acquired with a Philips Achieva 3.0 Tesla MRI scanner (Best, The Netherlands). We collected 3D T1-weighted images with CLEAR homogeneity correction with 1 × 1 × 3 mm³ resolution. In detail, the 3D T1-weighted gradient echo scan was acquired with TR = 28 ms, TE = 4 ms, 60 axial slices acquired at 3-mm slice thickness, in-plane voxel size = 1 × 1 mm², flip angle = 27°, and field of view (FOV) = 250 × 188 × 180 mm³. After structural image acquisition, 8 min of rs-fMRI data were acquired with an echo-planar imaging sequence with 3 × 3 × 3 mm³ resolution, 2,000-ms TR, 36 slices, 90° flip angle, and 240 volumes. Participants were instructed to close their eyes and to not think about anything in particular.

All subjects underwent 3D volumetric brain MRI scans. 3D T1 Turbo Field Echo (TFE) MRI data were acquired using an Achieva 3.0-Tesla MRI scanner (Philips, Best, the Netherlands), with a sagittal slice thickness of 1.0 mm, over-contiguous slices with 50% overlap and no gap, a repetition time of 9.9 ms, an echo time of 4.6 ms, a flip angle of 8°, and a matrix size of 240 × 240 pixels reconstructed to 480 × 480 over a field of view of 240 mm. Radiologists reviewed all MRI data for evidence of brain tumors, major infarctions (excluding lacunar infarctions), and hemorrhages (which are observed as low-intensity areas on T2-weighted images). The following parameters were used for the 3D FLAIR images: axial slice thickness of 2 mm; no gap; repetition time of 11,000 ms; echo time of 125 ms; flip angle of 90; and matrix size of 512 × 512 pixels.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
