Polycystic ovaries: MR imaging.
To determine the characteristic appearance of polycystic ovaries on magnetic resonance (MR) images, seven women with polycystic ovarian disease (PCOD) underwent MR examination of the pelvis. These MR images were compared with sonograms. Histologic material was available in two patients. Six of the seven women had characteristic, small peripheral cysts, best seen on T2-weighted MR images; these cysts were seen sonographically in only one case. The centers of nine of 14 ovaries were of low intensity with all MR pulse sequences; this low intensity corresponded with low echogenicity in six cases. Histologically, these areas correlated with hypertrophic cellular stroma. Coexisting central teratomas were seen in three ovaries. The ability of MR to display the findings of PCOD better than ultrasound and its ability to demonstrate coexisting pathologic conditions are valuable in imaging the female pelvis.
