Figure 4

A 51 year old woman with a seromucinous borderline tumor. Only the CNN could diagnose malignant tumors on the T2WI and the DWI (the CNN confidence value: malignant = 98.5% on T2WI; malignant = 99.9% on DWI). The CNN and reader 2 could diagnose malignant tumors on the ADC map (the CNN confidence value: malignant = 82.1%). On the other hand, the CNN and all radiologists could diagnose malignant tumors on the CE-T1WI (the CNN confidence value: malignant = 99.9%). This case was a typical image of seromucinous borderline or serous borderline tumor. There was almost no contrast between the papillary projections (arrow) showing hyperintensities on the T2WI and the contents of the cyst, and it was difficult to identify them, other than CE-T1WI, for the radiologists. ADC: apparent diffusion coefficient; CE-T1W1: contrast-enhanced T1-weighted imaging; CNN: convolutional neural network; DWI: diffusion-weighted imaging.
