Participants were scanned using a Siemens Skyra 3T scanner (Siemens Healthcare, Erlangen, Germany) with a 64-channel head and neck coil. As part of the scanning protocol, high-resolution T1-weighted images, three-dimensional fluid-attenuated inversion recovery (FLAIR) images, and a gradient echo field map were obtained. Acquisition parameters and analysis preprocessing details are described in the appendix (p 3).
We analysed structural MRI data using the Human Connectome Project (HCP) minimal preprocessing pipeline, as detailed elsewhere.20 (link) For each participant, mean cortical surface area and thickness were extracted from 360 parcels in the HCP-MPP1.0 parcellation.21 (link) Outputs of the preprocessing pipeline were visually checked for accurate surface generation by examining each participant's myelin map, pial surface, and white matter boundaries. Study personnel who processed the MRI images were masked to antisocial group membership.

For this study, a 3-Tesla Prisma MRI (Siemens, Germany) located at the National Brain Mapping Laboratory (NBML) and a 64-channel head and neck coil were used. An angled mirror was placed in front of patients so that they could see the display above the patient's head. A head support system and a pad were used to reduce the head movement and motion artifacts.
The patients underwent structural and functional imaging. A 3D T1-weighted image was created using 3D spoiled gradient-recalled (SPGR) sequence with voxel size = 1.1 × 1.1 × 1 mm3, TR = 1840.0 ms, TE = 2.13 ms, and total scan time = 4.10 min. For QSM imaging, a 3D gradient-recalled echo (GRE) sequence was used with voxel size = 0.9 × 0.9 × 2.0 mm3, TR = 45.0 ms, TE1 = 6.0 ms, number of echoes = 9, distance between echoes = 4 ms, and total scan time = 7 : 24.

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.
