MR images of the ectopic endometriotic lesions at different time points. On T1WI, the ectopic uterine tissues (EUTs) (arrow) appeared as irregular cystic mass with low signal (A). On axial FS-T2WI before injection (B), the EUTs appeared to have slightly high signal intensity surrounding with intermediate signals of fibrous walls. At 15 min (C), 30 min (D), 60 min (E), and 120 min (F) post-injection, the wall of lesions was more clearly outlined, and the lesion to background contrast was improved compared with (A).
