Figure 4

Repeatability and reproducibility of vessel length, mean diameter, mean sharpness measurements with bSSFP sequence. Bland-Altman plot shows good (A) intra-observer (r = 0.994), (B) inter-observer (r = 0.894), and (C) intra-class (r = 0.980) agreement between length measurements [mm] with low variability. Bland-Altman plot shows good (D) intra-observer (r = 0.990), (E) inter-observer (r = 0.977), and (F) intra-class (r = 0.959) agreement between mean diameter measurements [mm] with low variability. Bland-Altman plot shows good (G) intra-observer (r = 0.993), (H) inter-observer (r = 0.953), and (K) intra-class (r = 0.932) agreement between mean sharpness measurements [%] with low variability.
