Table 4. Absolute agreement among the six thresholding strategies for measuring the same quantitative parameter in the same scan.
| Quantitative parameter | ICC (95% CI) |
|---|---|
| FD number | 0.339 (0.124–0.601) |
| Area FD | 0.224 (0.063–0.468) |
| Average size FD | 0.000 (–0.090–0.191) |
| FD density | 0.278 (0.091–0.530) |
Mean value of the four acquisitions was considered in each pair. Values presented correspond to ICC. ICC, intraclass correlation coefficient; CI, confidence interval; FD, flow deficits.
