Intra- and inter-rater reliability presented as ICCs with 95% CIs, absolute mean maximal differences mm2, and ±SD for “All 4 measurements” and for “Measurements 2, 3 and 4” (first measurement excluded) for Examiners A and B (n = 48)

| By Examiner B (intra) | 0.998 (0.997–0.999) | 97 (78) |
| By Examiners A and B (inter) | 0.992 (0.923–0.998) | 117 (109) |
| B. Measurements 2, 3, and 4 | ||
