Bland-Altman plots demonstrate agreement among ke of at least 0.04 cycles/mm. The first, second, and third rows contain Bland-Altman plots for circumferential strain (Ecc), radial strain (Err), and twist (θ), respectively. The subscript values denote the comparisons between acquisitions with the stated ke. The inter-test comparison was between two acquisitions with ke of 0.10 cycles/mm. The shaded areas denote the region within the 95 % limits of agreement. The worst agreement was seen between 0.02 and 0.10 cycles/mm
