Susceptibility-Weighted Imaging for the Evaluation of Gynecologic Diseases

Mayumi Takeuchi¹, Kenji Matsuzaki¹, Hiromu Nishitani¹

We evaluated various gynecologic diseases by susceptibility-weighted imaging (SWI). Punctate or curved linear signal voids along the cyst wall due to hemosiderin deposition were characteristic for endometriomas, and were not be observed in non-endometrial benign cystic masses. SWI was also useful for the diagnosis of extra-ovarian endometriosis and adenomyosis by detecting hemosiderin deposition, of red degenerated leiomyoma at early phase by detecting intravenous deoxyhemoglobin, and of other pathologies with hemorrhage.
