Imaging was performed on three generations of 3T Siemens scanners: Allegro 3T with a 6-channel headcoil, Trio 3T with a 12 channel headcoil, and Trio 3T with a 32 channel headcoil. The DTI data acquisition and preprocessing are fully described (Kochunov et al 2016b (link)). All data passed QA control of <3 mm accumulated motion during the scan. There was no significant difference in the head motion parameters between patient and controls. The HARDI data was processed using a tract-based spatial statistics (TBSS) method, distributed as a part of FMRIB Software Library (FSL) package (Smith et al 2006 (link)). The population-based DTI cerebral WM tract atlas developed at John Hopkins University and distributed with the FSL package (Wakana et al 2004 (link)) was used to calculate average FA values along the spatial course of major WM tracts as described elsewhere (Kochunov et al 2011a (link), Kochunov et al 2011b (link), Kochunov et al 2012 (link)). Whole brain averaged FA was the primary measure. The DTI association analysis included 313 subjects (96 SSD, 199 controls and 18 with affective disorders with psychotic features). For the rs8234 fractional anisotropy association analysis, two subjects were excluded for missing genotype data.

Functional MRI images were collected using a Siemens 3T Trio scanner (Siemens Medical Systems, Erlangen, Germany) with a 12-channel head coil. The 242 whole-brain resting-state functional images were obtained with the following parameters: TR/TE = 2000 ms/30 ms, FA = 90°, FOV = 220 mm × 220 mm slices = 32, thickness = 3 mm, slice gap = 1 mm, acquisition voxel size = 3.4 mm × 3.4mm × 3.4 mm. During resting-state scanning, the participants were instructed to lie down with their eyes closed and to remain awake without thinking of anything special. High-resolution 3D T1-weighted structural images were obtained using a Magnetization Prepared Rapid Acquisition Gradient-echo (MPRAGE) sequence: TR/TE = 1900 ms/2.52 ms, FOV = 256 mm × 256 mm, FA = 9°, slices = 176, thickness = 1 mm, and voxel size = 1 mm × 1 mm × 1 mm.

MRI of the neck was performed on a Siemens 3T Trio magnetic resonance system using phased-array neck and body matrix coils. A volumetric 3D Dixon gradient-echo multiecho pulse sequence with 6 echo times (repetition time = 20 ms; echo time = 2.46, 6.15, 9.84, 12.3, 14.76, 17.22 ms; flip angle = 5; slice thickness = 3 mm; field of view = 42 cm; matrix = 256 × 256) was employed. Sagittal images were reconstructed to identify the level of C7 vertebral body. Axial images at the level of C7 were reconstructed and used for measurement of dorsocervical adipose tissue area. Vertical reference lines were placed along the lateral border of the vertebral body of C7 and projected over dorsocervical adipose tissue, providing standardized lateral boundaries for the fat depot. Dorsocervical adipose tissue was demarcated anteriorly by the paraspinal muscles and posteriorly by the dorsocervical skin. Area measurements within these boundaries were expressed in square centimeters. In addition, MRI was acquired using an axial T1-weighted, fat-suppressed pulse sequence obtained at the level of L4 vertebral body for determination of visceral and subcutaneous fat areas utilizing commercial software (Vitrak, Merge e/Film).

MR data were collected on a Siemens Medical Systems 3T Trio. A 3D T1-weighted “MPRAGE” RF-spoiled rapid flash scan in the sagittal plane, and a T2/PD-weighted multi-slice axial 2D dual Fast Turbo spin-echo scan in the axial plane was used. The multi-echo whole brain T1 scans had 1mm isotropic voxel size and sufficient field of view to cover from the top of the head to the neck with the following protocol parameters: TR=2530ms, TE1=1.74ms, TE2=3.6ms, TE3=5.46ms, TE4=7.32ms, flip angle=7°. All functional runs were acquired using gradient echo, echo-planar images with the following protocol parameters: TR=1850ms, TE=30ms, flip angle=75°. Volumes were consisted of thirty-four 3 mm slices with transversal orientation. Each volume covered the whole brain with FOV=208mm and 64X64 matrix, resulting in 3.3×3.3×3 mm³ voxel size.

The clinical dataset comprised 189 glioblastoma patients aged 21 – 86 (average 61 years), which was retrospectively identified in the Washington University School of Medicine (WUSM) neurosurgery brain tumor database. Inclusion criteria included: a new diagnosis of primary glioblastoma; age above 18 years; MRI at WUSM including fMRI for pre-surgical planning; adequate tumor segmentation; IDH1 wild-type; and root mean square head motion < 1.15 mm (Table C.1). Exclusion criteria included: prior brain surgery and inability to have an MRI scan. The Washington University Institutional Review Board oversees all aspects of the study. All analyses were conducted retrospectively using preoperative data.
Patients were scanned with either a 3 T Trio or Skyra scanner (Siemens, Erlangen, Germany) using a standard clinical pre-surgical tumor protocol. Anatomical imaging included a T1w magnetization prepared rapid acquisition (MP-RAGE) and a T2w fast spin echo, both with a voxel size of (1 mm)³ and a FLAIR image used for tumor segmentation. rs-fMRI was acquired using a BOLD-sensitized EPI sequence (voxel size (3 mm)³ isotropic; echo time = 27 ms; repetition time = 2.2 – 2.9 s; field of view = 256 mm; flip angle = 90°). Two rs-fMRI runs were obtained in each patient (320 frames); each run included 160 frames.

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.
