MRI was performed using a 3.0 T scanner (Philips Achieva, The Netherlands) with an 8-channel SENSE phased-array head coil and a 16-channel receive-only neuro-vascular spine coil. The MRI protocol included a brain axial dual echo TSE and a brain sagittal 3D T1-weighted turbo field echo sequences as previously described^{7 (link)}. The spine sagittal T2- weighted TSE sequence was acquired as following: TR = 4,097 ms, TE = 120 ms, FOV = 250 × 250 mm, matrix size = 512 × 512, 13 3 mm-thick slices. Brain T2 and T1 lesion volumes (LV) were measured as described before^{17 (link)}. Cerebellar lesion loads were measured on dual echo/3D T1 scans following the same steps applied for whole brain LV quantification. Two time-point percentage brain volume change (PBVC) was computed with SIENA^{18 (link)} on T1-weighted-lesion-filled and non-uniformity corrected images. Cerebellar cortical and WM volumes were measured using Freesurfer v5.3.0 longitudinal pipeline^{19 (link),20 (link)}.

Brain Imaging Protocol for Motor Sequence Learning

After the dummy task, and before the motor sequence learning task, subjects underwent brain MRI on a 3.0 Tesla scanner (Philips Achieva, The Netherlands) with an 8-channel SENSE phased-array head coil. The MRI protocol included T2-weighted Turbo Spin Echo sequence (TR/TE = 3000/80 ms; FOV = 230 mm × 230mm; matrix = 512 × 512; slice thickness = 4 mm), 3D T1-weighted Turbo Field Echo sequence (TR/TE/TI = 7.5/3.4/900 ms; voxel size 1×1×1 mm³). For rs-fMRI, a total of 120 volumes were acquired in a transverse plane using a T2*-weighted echo-planar-imaging sequence (TR/TE = 2607/27 ms; flip angle = 90°; FOV = 210 mm × 210 mm; matrix = 96 × 96; slice thickness = 3 mm; voxel size = 2.19 mm × 2.19 mm × 3 mm). The rs-fMRI settings provided 0.19 Hz bandwidth with 3.5 × 10^-3 Hz resolution, which is adequate to select the 0.01-0.1 Hz band of interest (see rs-fMRI analysis below). Each EPI volume included 50 axial slices without gap, covering the entire cerebral cortex and cerebellum. During rs-fMRI, the subjects were instructed to stay still, with their eyes closed, awake but not engaging in any specific mental activity.

All patients and healthy controls were scanned at the Birmingham University Imaging Centre (BUIC) on a 3T Philips Achieva MRI system with 8--channel phased array SENSE head coil.
We acquired anatomical scans using a sagittal T1--weighted sequence (sagittal orientation, TE/TR (echo time/repetition time)=3.8/8.4ms, voxel size 1x1x1mm 3 ). Taking into account that some patients presented with neurodegenerative changes and some with damage following carbon monoxide poisoning if possible we also acquired an additional scans using T2 FLAIR (Fluid Attenuated Inversion Recovery) sequence (TR=11000ms, TE=125ms, voxel size 0.45x0.44x2 mm 3 ).
While T1 scans were used in VBM analyses and lesion reconstruction, FLAIR scans were used to verify lesion demarcation (see below).

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.
