Brain Tumor Connectomics Data

Post-operative data of 7 glioma patients, 12 meningioma patients (1 [sub-PAT11] with bad data quality) and 10 control subjects. Out of the 11 glioma patients, 14 meningioma patients, and 11 healthy controls that were included pre-surgically ("BTC_preop, ds001226" on OpenNeuro), 7 glioma patients (1 drop-out, 1 no resection, 2 end of study), 12 meningioma patients (1 drop-out, 1 MRI not possible because of cochlear implant), and 10 healthy controls (1 drop-out) agreed to participate post-operatively.

Compared to the initial database, 6 patients were excluded: 2 because of glioma grade 4, 3 because of subtentorial tumor, 1 because of absence of MRI data (subdural grid).

Of all subjects the following data were acquired: - T1w MPRAGE anatomical scan (anat) - resting-state fMRI (func) - multi-shell HARDI diffusion-weighted MRI (dwi, acq=AP) - short DWI with reverse phase encoding directions (dwi, acq=PA) - cognitive assessment using the Cambridge Neuropsychological Test Automated Battery (CANTAB): MOT, RVP, RTI, SSP & SOC - questionnaires assessing demographic information, lifestyle habits & emotional functioning

The "derivatives" folder contains

• tumor masks, obtained with a combination of manual delineation and disconnectome
• time series, structural and functional connectivity matrices, and resting state HRF for each ROI. The structural connectivity (SC) is derived with the TVB pipeline (https://github.com/BrainModes/TVB-empirical-data-pipeline) with manual segmentation when necessary. The regions are according to the Desikan-Killiany atlas. The resting state HRF is obtained with the toolbox described here Wu GR, Colenbier N, Van Den Bossche S, Clauw K, Johri A, Tandon M, Marinazzo D. rsHRF: A toolbox for resting-state HRF estimation and deconvolution.
