R2* and automatically
quantitative ITSS had good performance in differentiating between
MOTs and OOTs. The combination of the two parameters improved the differential
diagnosis efficiency.

ovarian cancer. (1a) T2WI image; (1b) R2* map; (1c) phase map; (1d) tumor was
delineated around the edge of the tumor; (1e) AS software recognized
quantitatively and automatically ITSS ratio by reading phase maps. ITSS
recognized were covered in green.
