From: Machine learning combined with radiomics and deep learning features extracted from CT images: a novel AI model to distinguish benign from malignant ovarian tumors

Fig. 5

Contrast-enhanced CT images of ovarian tumors that were misclassified by AI model or/and junior radiologists. a A malignant ovarian tumor (clear cell carcinoma) that was predicted to be benign by AI model but malignant by all junior radiologists. The solid portion (arrow) in the tumor is a clue for malignancy in radiological evaluation. b A benign ovarian tumor (endometrioma) that was predicted to be malignant by AI model but benign by all junior radiologists. There was no solid portion, mural nodule, or thick septa to indicate malignancy in radiological evaluation. c A benign ovarian tumor (mucinous cystadenoma) that was predicted to be malignant by both AI model and all junior radiologists. d A benign ovarian tumor (mucinous cystadenoma) that was predicted to be malignant by all junior radiologists but benign by AI model. Thick septa (arrow) in c and d raised the suspicion of malignancy in radiological evaluation
