  1. Information that has not explicitly been specified in the cited publication is indicated by —. Information that has not clearly been explained in detail is indicated by †. The size of the test set is shown as the total number of 2D slices or 3D scans taken from a specified number of unique patients that was used for quantitative evaluation of the method. For example, Liao et al. included a single scan for each unique patient and from each scan a single slice was taken for evaluation. Numbers in parentheses indicate the number of cases containing pathology in a test set also containing healthy subjects.
