T2-star weighted imaging contributes to differential diagnoses of T1WI-hyperintense cystic masses, solid portion within them, and extra-ovarian endometriosis. T2-star weighted imaging to routine exam improves sensitivity for pelvic adhesion, which contributes to better preparation of surgery. Hypointensity within non-endometrial cystic ovarian masses reflect chemical-shift artifact in dermoids, and subtle endometriosis in other tumors.

Pelvic T2-star weighted imaging Why add T2*WI to pelvic examinations Setting parameters The normal pelvis on T2*WI Endometriosis Spectrum of imaging findings Extra-ovarian endometriosis Solid part of endometriomas Pelvic adhesion Prediction of dorsal adhesion: ovary and Douglas pouch Prediction of ventral adhesion: uterus, bladder and abdominal wall False positives and negatives Cystic ovarian tumors Dermoids Serous and mucinous cystadenomas Other cystic masses Conclusions
