fidoptUT-EndoMRI, uterus and ovaries on T2 fat-sat MRI
Pelvic T2-weighted fat-suppressed MRI of one subject from the Texas Children’s Hospital Pavilion for Women subset of UT-EndoMRI, with the uterus and the ovaries contoured by hand.

- Truth. One obstetrician-gynecologist assistant, supervised by an expert gynecologist, contoured the masks: not a consensus. The source paper reports limited agreement between raters on ovarian boundaries in the separate D1 subset.
- Labels. The ovaries form one label, with no side; endometriomas and cysts are not scored. Voxels where the uterus and ovary masks overlap are ignored rather than given to one organ.
- Images. The T2FS as delivered, its intensities, geometry and thick slice spacing kept, nothing resampled or registered; predictions are scored in that geometry.
- Duplicates. D2-007 and D2-009 share one T2FS image byte for byte, with different masks: D2-007 is kept, and D2-014 fills the tenth development place. The twenty images drawn have distinct voxel digests, which rules out a duplicate image, not a shared patient; the images not drawn were not all compared.
- Outside numbers. The article and the README disagree on whether the first 38 identifiers were for training or testing, so no published, model-independent test claim is made for them.
- Licence. Zenodo says CC BY 4.0, but the archive README and the record's user agreement allow only non-commercial scientific research, with citation: the dataset stays off the open commercial-use leaderboard.

About the data
- Test cases
- 10 test subjects drawn with seed 2026 among eligible D2 identifiers 038 and later, which the archive README says were not used for RAovSeg development, and 10 development subjects among those below 038 in the seeded order, D2-009 left out as a duplicate. Eligible means the T2FS image and both the ut and ov masks.
- Truth
- contours by experts Dataset 2 masks manually contoured on T2-weighted fat suppression MRI by an obstetrician-gynecologist assistant supervised by an expert gynecologist. The ov mask combines the ovaries; laterality is not inferred. Endometriomas and cysts have separate provider files and are not scored here.
- Licence
- Zenodo metadata: CC BY 4.0; archive README and record user agreement: exclusively non-commercial scientific research, with citation. Both are recorded and the non-commercial restriction is retained.
