Fig 1.
Workflow displays different processing steps and each methods duration in minutes (‘). Segmentation-based analysis by operator 1 (SBA 1) included four major segmentation steps, operator 2 (SBA 2) displayed three steps. Model-free analysis (MFA) did not include a segmentation and used the entire field of view as seeding area for deterministic fiber tracking. Within MFA the red cross symbolises the manual exclusion of tracts outside of the highlighted supraspinatus muscle (blue color).

Violin plots and mean differences between methods.
Violin plots show mean differences between segmentation-based analysis (SBA 1 [blue] and SBA 2 [red]) and model-free analysis (MFA, yellow).

Bland-Altman plots and limits of agreement.
Bland-Altman plots for interrater-reliability for segmentation-based analysis by two different operators (SBA 1 and SBA 2). and model-free analysis (MFA). The x-coordinate shows the mean of two methods and the y-coordinate shows the value differences between each method. The middle black line shows the mean of the paired differences. The dashed line presents the limits of agreement.
