A comparison of navigator-gated and breath-held high-resolution T
maps in healthy volunteers. a,b. The standard navigator-gated T2 map and breath-held SKRATCH T2 map respectively. Note that the maps are homogeneous and have similar myocardial surface available for analysis. The color bar indicates the T2 relaxation time in ms. c. The mean T2 values and standard deviations of the 17 healthy volunteers show a slight increase in standard deviation for the breath-held SKRATCH acquisition. d. The Bland-Altman analysis of the difference in mean T2 values for 11 volunteers. The dotted line represents the mean with a bias of 0.28, while the continuous lines represent the 95% confidence interval (1.96 × standard deviation).
