Fig. 3A —Graphs show accuracy of automated polyp measurement tool. Mean absolute error represents pooling of data across all four reviewers and all CT data sets. When multiple polyp characteristics associated with measurement inaccuracy are combined (e.g., small size, flat morphologic type, location on tip of haustral fold), measurement errors can be large. Graph shows accuracy of measurement of polyps not on tip of fold.
