The comparison of diagnostic performance of the radiomics classifiers and clinical classifier in the training cohort [(A) First Affiliated Hospital of Zhejiang University School of Medicine (FAH-ZJU)] and independent validation cohorts [(B) Shulan Health (Hangzhou) Hospital (SLH); (C) Lishui Central Hospital (LSCH)]. The performance was measured by the area under the receiver operating characteristic (AUROC) curve. The radiomics classifiers consisted of the combined classifier (purple line), the T2 classifier (green line), and the diffusion-weighted imaging (DWI) classifier (orange line). The clinical classifier was shown as the red line.
