| # RESECT + RESECT-SEG |
|
|
| Combined re-host of the **RESECT** image database (Xiao et al. 2017) and the |
| **RESECT-SEG "All-Labels"** segmentations (Behboodi et al. 2024, OSF `jv8bk` v1 |
| 2024-02-15) — 23 low-grade glioma (WHO grade II) resections at St. Olavs |
| University Hospital, Trondheim (2011-2016). Pre-operative MRI (Gd-T1w, T2-FLAIR, |
| 1 mm iso) and reconstructed 3D intra-operative B-mode ultrasound at three |
| timepoints (before / during / after resection; per-case isotropic grids, |
| 0.14-0.27 mm). Case IDs are `Case1-8, 11-19, 21, 23-27` (9, 10, 20, 22 were |
| never released). |
|
|
| ## Annotated tasks (181 image-mask pairs, `train.jsonl`) |
|
|
| | task | structure | volume | pairs | note | |
| |---|---|---|---|---| |
| | `tumor-us-before` | tumor | US before | 23 | primary CuRIOUS 2022 task | |
| | `resection_cavity-us-during` | resection cavity | US during | 21 | Case11+15 absent (blood-filled cavity, border indistinguishable) | |
| | `resection_cavity-us-after` | resection cavity | US after | 22 | Case11 absent | |
| | `tumor-flair` | tumor | pre-op FLAIR | 23 | int16 {0,1} masks | |
| | `sulci-us-{before,during,after}` | sulci | US x3 | 23+23+23 | | |
| | `falx-us-{before,during,after}` | cerebral falx | US x3 | 8+7+8 | only Cases 2,12,14,15,19,21,23,26; during missing for 26 | |
|
|
| Every mask sits on the **exact native grid of its image** (identical shape and |
| affine). Masks are binary {0,1} uint8 (FLAIR-tumor: int16). The 23 Gd-T1w |
| volumes carry no annotations (context only). An **absent mask file means the |
| structure was not annotated for that volume** — unlike the frozen CuRIOUS 2022 |
| release (OSF `6y4db`), which shipped 3 of these as all-zero volumes. The jv8bk |
| masks are the authors' recommended, revised tier (not voxel-identical to 6y4db). |
|
|
| ## Layout |
|
|
| ``` |
| dataset/Case{N}/ Case{N}-{T1,FLAIR,US-before,US-during,US-after}.nii.gz + all masks |
| landmarks/Case{N}/ MRI<->US / US<->US homologous landmark .tag files (registration) |
| train.jsonl one row per pair: case_id, task, structure, modality, timepoint, |
| image, mask, shape, spacing_mm (single split; no official split exists) |
| ``` |
|
|
| ## Licensing |
|
|
| - **Images** (RESECT, NIRD archive, DOI [10.11582/2017.00004](https://doi.org/10.11582/2017.00004)): **CC BY 4.0** |
| - **Masks** (RESECT-SEG, [osf.io/jv8bk](https://osf.io/jv8bk/)): **CC BY-NC-SA 4.0** — "gaining any |
| financial benefits from the distribution of the proposed annotation dataset is prohibited" |
| - Combined repo therefore carries **CC BY-NC-SA 4.0** (the more restrictive component). |
|
|
| ## Benchmark contamination warning |
|
|
| These 23 patients ARE the training data of **CuRIOUS 2018/2019/2022** and (as |
| the resampled 22-case `EASY-RESECT` variant) of **Learn2Reg 2020**. Any model |
| trained on those challenge releases has seen these cases; cross-reference by |
| `case_id`. The challenges' private test cases (10 in 2018/19, 6 in 2022) were |
| never publicly released. No patient overlap with BITE, ReMIND, BraTS, MSD, or |
| TCIA collections. Note: `EASY-RESECT`'s `*-seg.nii.gz` files are voxelized |
| landmark spheres, NOT anatomy — they are unrelated to these masks and are not |
| included here. |
