Fig. 7

Intraclass correlation coefficient and Bland–Altman plots measuring the similarity of global mean AT and RT. Top panels show the intra-class correlation coefficient plots while bottom panels show the Bland–Altman plots comparing mean AT and RT for intra-observer tests (r = 0.95 for AT and 0.98 for RT); inter-observer tests (r = 0.97 for AT and 0.98 for RT); and scan re-scan studies (r = 0.96 for AT and 0.76 for RT).
