Figure 1.

Bland-Altman plots using the first (left) and second (right) ranked automatic segmentation methods’ volumes from the 2015 Longitudinal Lesion Challenge are presented. We show plots comparing volumes obtained from the automatic and manual methods. The manual volumes were delineated by rater 1 (top) and rater 2 (bottom). Using the differences, we highlight the mean (blue) plus and minus 1.96 times the standard deviation (red). Each subject is represented in a unique color and each point represents a subject-time point. There are fourteen unique subjects with at least four follow-up imaging sessions.
