icobrain tbi for CT, used in acute TBI

info qc visualResults brainVolumes softwareVersion
  • INFO

    CT date = date of the CT scans on which the report is based.

  • QC

    Status (Approved / Approved with remarks / Rejected / Unusable) and remarks on the quality of the original images and the computed values.

  • VISUAL RESULTS
    • Left: suprasellar (green), quadrigeminal (lavender) and prepontine and ambient (orange) cisterns are depicted in the axial plane.
    • Mid: mass lesion (red) segmentations are depicted in the axial plane.
    • Right: midline shift = A (green)/2 – B (red)
  • MASS EFFECTS

    Cisterns (volumes) are normalized for head size. The normal range and normative percentiles serve as a reference based on control population with normal cisterns.

    Cisterns (bull’s eye) compares cisternal volumes with the age-matched population statistics (median, percentile 10 and 1) for each cistern. Red represents the level of measurement error computed from test-retest experiments.

    Hyperdensities indicate the total volume and volume of the largest component in ml

    Midline Shift
    displacement (A/2 –B) in mm

icobrain tbi for MRI, used in monitoring TBI

info qc visualResults brainVolumes softwareVersion
  • INFO

    MRI dates = dates of the MRI scans on which the report is based. When only one MRI exam is available, a baseline report is created which reports volumes but no volume changes.

  • QC

    Status of semi automated quality control (Approved / Approved with remarks / rejected) and remarks on the quality of the original images and the segmentation.

  • VISUAL RESULTS

    Color-coded segmentation of FLAIR white matter (WM) hyperintensities

    • Subcortical (blue)
    • Cerebellum (green)
    • Corpus Callosum (yellow)
    • Brain stem (purple)

    This segmentation is also available in DICOM format.

  • BRAIN VOLUMES

    Brain volumes are corrected for head size. The normal range and normative percentiles serve as a reference based on healthy controls.
    Annualized volume change describes the percentage of brain volume change per year compared to the previous scan. The normal annualized volume change represents the average expected annual volume change for a healthy age- and gender-matched person.

    Population graphs show the age- and gender-matched average and normal ranges for each substructure. The current (black) and previous (white) time points are marked with an ‘x’. The error bars are computed from the pooled results of several test-retest experiments. They represent the interval in which the differences between test- and retest results can be found with 90% confidence.

    Regional FLAIR WM hyperintensities volume chart shows the volumes and error bars at time point 1 (t1), time point 2 (t2) and the change () for each location. The error bars are computed from the pooled results of several test-retest experiments. They represent the interval in which the differences between test- and retest results can be found with 90% confidence.
    Volume change = total difference in volume compared to the previous scan
    New + Enlarging – Shrinking (includes disappearing) = Volume change
