Fig. 6From: The effects of volume of interest delineation on MRI-based radiomics analysis: evaluation with two disease groupsPrediction performance of the radiomics models across different VOIs-operated validation data. NPC group: (a) CET1-w images and (b) T2-w images; SLN group: (c) DWI and (d) T2-FS images. Note that the abbreviation marked with an asterisk represents a training model. For example, Erosion* is the training model built with data and parameters obtained from VOIs with erosion. The results in the first row represent the prediction performance of the Baseline model tested by different VOIs-operated dataBack to article page
