Use-cases supported =============================== VisualQC supports the following use cases: * Functional MRI scans (focused visual review, with rich and custom-built visualizations) * Freesurfer cortical parcellations (accuracy of pial/white surfaces on T1w mri) * Structural T1w MRI scans (artefact rating) * Volumetric segmentation accuracy (against T1w MRI) * Registration quality (spatial alignment) within a single modality (multimodal support coming) * Defacing accuracy More detailed specifics for each modality are noted below: Structural MRI use-cases ---------------------------- - Checking the accuracy of white and pial surfaces (from Freesurfer and other algorithms) - Evaluate the accuracy of defacing or skull-stripping - Assess the accuracy of voxel-wise ROI or tissue segmentation (subcortical structures, gray matter, white matter or CSF masks) - Inspect the quality of raw T1 MRI scan (for motion, ringing, ghosting, or other artefacts) - Comparison of the registration quality or accuracy of the spatial alignment. Functional MRI use-cases ---------------------------- - Visual review of scan quality, identification of artefactual frames (motion, spikes, etc) - Quality control of the impact of different pre-processing steps Diffusion MRI use-cases ---------------------------- - Visual review of scan quality, identification of artefactual gradients (motion, spikes, etc) - Quality control of the impact of different pre-processing steps Registration/Alignment use-cases -------------------------------- - Within-modality assessment of the accuracy of the spatial alignment - e.g. T1w to T1w, EPI to EPI etc. - Cross-modal comparison coming soon. **Other modalities to be supported soon.**
