Table 3 Evaluation of arachnoid granulation labelling over different metrics of interest and comparison to gold standard manual segmentation. Results are expressed using Pearson’s correlation coefficient, uncorrected p-values are reported in parentheses, and root mean square (RMS) difference (standard deviation in parenthesis). The RMS is expressed in mm3 for all volumetric measures (i.e., total, average, maximum, and minimum), and by number of occurrences for count
| Â | Total Volume | Count | Average volume | Maximum volume | Minimum volume |
|---|---|---|---|---|---|
R (p-value) | 0.97 (< 0.001) | 0.90 (< 0.001) | 0.80 (< 0.001) | 0.80 (< 0.001) | 0.82 (< 0.001) |
RMS (std) | 21.27 (37.57) | 1.17 (1.46) | 3.83 (6.11) | 12.83 (26.32) | 1.09 (0.86) |
