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.
