Assessment of MRI-Based Radiomics in Preoperative T Staging of Rectal Cancer: Comparison between Minimum and Maximum Delineation Methods

Figure 4

Decision curve analysis (DCA) of the two schemes of delineation. DCA showed that at the probability threshold of 0.0 to 0.9, the SVM model based on the maximum algorithm provided more net benefit than utilizing the minimum delineation scheme. Model 1: minimum delineation method; Model 2: maximum delineation method.
