Example of solid tissue descriptors: a Axial T2-weighted sequence without fat saturation. b Axial unenhanced T1-weighted Water sequence showing papillary projections in bilateral serous borderline ovarian lesions (arrows). c Axial T2-weighted sequence without fat saturation. d Axial unenhanced T1-weighted Water sequence showing a large mural nodule (arrows) in a high-grade serous ovarian cancer. e Axial T2-weighted sequence without fat saturation. f Axial unenhanced T1-weighted Water sequence showing irregular septations (arrows) in bilateral serous borderline ovarian lesions. g Axial T2-weighted sequence without fat saturation. h Axial unenhanced T1-weighted Water sequence showing irregular wall (arrows) in a serous borderline bilateral ovarian tumor. i Axial T2-weighted sequence without fat saturation. j Axial unenhanced T1-weighted Water sequence showing irregular septations showing large solid component (arrows) high-grade serous ovarian cancer
