All data were acquired on the same Siemens MAGNETOM Tim Trio 3 T scanner with a 32-channel head coil. High-resolution T1-weighted images were acquired using a MPRAGE sequence (176 slices; FOV = 256; TR = 2530 ms; TE = 3.32 ms; voxel size = 1 × 1 × 1 mm). Two sets of diffusion-weighted images (64 directions; b-value = 1000 s/mm2; FOV = 256; TR = 8700 ms, TE = 92 ms; voxel size = 2 × 2 × 2 mm), along with two images with no diffusion gradient applied (b-value = 0), were also acquired. In addition to structural scans, resting-state fMRI data were collected in the same scanning session. A gradient-echo planar imaging sequence sensitive to blood-oxygen-level dependent contrast (282 volumes; 33 contiguous axial slices; TR = 2190 ms; TE = 30 ms; voxel size = 3 × 3 × 3.6 mm) was used. During the resting-state fMRI scan the subjects were asked to fix their gaze on the point displayed on the screen and to relax, but not fall asleep.

Imaging data were acquired on a Magnetom Tim Trio 3T scanner (Siemens, Munich, Germany) using blood oxygen level-dependent (BOLD) and three-dimensional T1-weighted magnetization prepared rapid acquisition gradient echo (MPRAGE) sequences. Scanning parameters for BOLD and three-dimensional (3D) T1 MPRAGE sequences are documented in our previous studies (Zhang et al., 2018 (link), 2020a; 2021 (link)). Briefly, for the BOLD sequence, the parameters were as follows: repetition time (TR) = 2,400 ms, echo time (TE) = 30 ms, field of view (FOV) = 230 mm × 230 mm, matrix size = 64 × 64, time points = 240, flip angle = 90°, and 40 axial slices. Patients were instructed to remain calm and awake with eyes closed during the resting-state fMRI scanning. For the 3D T1 MPRAGE sequence, the parameters were as follows: voxel size = 1.0 mm × 1.0 mm × 1.0 mm, FOV = 256 mm × 256 mm, matrix size = 256 × 256, thickness/gap = 1.0/0 mm, TR = 2,300 ms, TE = 2.98 ms, flip angle = 9°, and 176 sagittal slices.

Functional images as well as high-resolution structural images were acquired on Siemens Magnetom TIM Trio 3 T scanner (Siemens Healthcare). In both studies, an RS scan of about 9 min duration was performed as the second scan of the protocol following a fieldmap. We used a T2*-weighted gradient echo planar (EPI) sequence with 36 transversal slices oriented parallel to the AC–PC line (whole-brain coverage, TE = 30 ms, TR = 2250 ms, flip angle 70°, slice thickness 3.0 mm, matrix 192 × 192, FOV 192 mm, in-plane resolution 2.6 × 2.6 mm). Participants were instructed to close their eyes, relax and let their mind flow. A high-resolution structural scan was performed as fourth scan of the sequence. We used a T1-weighted 3D MPRAGE sequence (160 sagital slices, slice thickness = 1 mm, TE 291 ms, TR 2300 ms, TI delay 900 ms, FA 9°, FOV 256 × 256 mm).

All images were acquired on a Siemens MAGNETOM Tim Trio 3 T scanner (Erlangen, Germany) using a 32-channel head coil. The T1 weighted images were obtained using a three-dimensional T1-weighted magnetization prepared gradient-echo sequence (MPRAGE) based on the ADNI protocol (www.adni-info.org) (repetition time (TR) = 2500 ms; echo time (TE) = 4.77 ms; TI = 1100 ms, acquisition matrix = 256 × 256 × 176, flip angle = 7°; 1 × 1 × 1 mm voxel size). Diffusion-weighted images were obtained with a single-shot diffusion-weighted spin-echo-refocused echo-planar imaging sequence (field of view (FOV) 218 mm × 218 mm; 128 × 128 matrix interpolated to 256 × 256; TE = 98 ms; TR = 11000 ms; 73 slices; slice thickness 1.7 mm; b-value 1000 s/mm2; 60 directions). Magnetisation transfer (MT) images were acquired consisting of two volumes acquired with identical settings (transversal, 256 × 256 pixels, TE = 5.5 ms, TR = 28ms 48 slices, voxel size 1mm × 1mm × 3mm). The first image (MT image) was acquired with a magnetic saturation pulse (1200 Hz off-resonance, 16 ms) and the second without (noMT image) a magnetic saturation pulse resulting in a proton-density-like image.

T1 MRI outcomes were acquired with a Siemens Magnetom TIM Trio 3T scanner using a 4-channel Siemens large flex coil (516 mm × 224 mm, Siemens, Munich, Germany) for 18 of the 21 participants. Due to a MRI systems upgrade in our Biomedical Research Imaging Center, the 12 month T1ρ MRI outcomes for 3 of the 21 participants were acquired using a Siemens Magnetom Prisma 3T PowerPack scanner with a XR 80/200 gradient coil (60 cm × 213 cm, Siemens, Munich, Germany). Inter-scanner reliability was assessed in 6 knees using intra-class correlation coefficients (ICC), which were found to be within an acceptable range (ICC≥0.75) for all regions of interest. Additionally, all T1ρ relaxation times in the ACLR limb were normalized to the regions of interest in the uninjured contralateral limb for each participant thereby minimizing any effect from utilizing multiple MRI scanners. Prior to acquiring MR images, participants remained seated for 30 minutes to unload the knee cartilage.(27 (link)) We used a T1ρ prepared three-dimensional Fast Low Angle Shot (FLASH) with a spin-lock power at 500Hz, five different spin-lock durations (40, 30, 20,10, 0 ms) and a voxel size of 0.8mm × 0.4mm × 3mm (field of view= 288mm, slice thickness=3.0mm, TR= 9.2ms, 160 × 320 matrix, gap= 0mm, flip angle=10°, echo-train duration time= 443ms, phase encode direction of anterior/posterior).

Check if the same lab product or an alternative is used in the 5 most similar protocols
We used a Siemens Magnetom Tim Trio 3 T scanner equipped with a 32-channel head coil. Each experimental session consisted of two scans of echo-planar-imaging (EPI): one scan before the ball-rotation task (rs-fMRI_pre; ~7.6 min) and one scan after (rs-fMRI_post; ~7.6 min). Each scan was acquired with a total of 200 whole-brain volumes using the following parameters: acquisition matrix 64 × 64, 3 mm isotropic voxel, 1 mm gap between slices, 34 slices, TR = 2300 ms. For co-registration, we acquired T1-weighted anatomical images (MP2RAGE; ~5.12 min) before the ball-rotation task with the following parameters: voxel size = 1 mm × 1 mm × 1 mm, 176 sagittal slices, FOV = 256 × 240 mm. Participants were instructed to relax but to stay awake while keeping their eyes closed during image acquisition.

Participants were scanned using a Siemens MAGNETOM Tim Trio 3T scanner (32-channel head coil) at the Wolfson Brain Imaging Centre, Cambridge. The brain imaging session started with a high resolution T1-weighted, magnetisation-prepared rapid gradient-echo (MPRAGE) structural scan (TR = 2300 ms, TE = 2.98 ms, slice thickness = 1.00 mm). The echo planar imaging sequence parameters for the 8.73-min eyes-closed resting-state functional data acquisition were as follows: 32 slices in each volume, 3.0 mm slice thickness, 3.0 × 3.0 × 3.0 voxel size, TR = 2000 ms, TE = 30 ms, flip angle = 78 degrees, 262 volumes. The MRI data preprocessing pipeline included slice-time and motion (six degrees of freedom) corrections, co-registration to the high resolution T1-weighted structural image, normalisation to the Montreal Neurological Institute (MNI) space through the unified segmentation–normalisation algorithm (Ashburner & Friston, 2005 (link)) and smoothing with an 8 mm FWHM Gaussian kernel using the SPM software package (Version 12.0) (http://www.fil.ion.ucl.ac.uk/spm/), based on the MATLAB platform (Version 15a) (http://www.mathworks.co.uk/products/matlab/).

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.
