Evaluation of nodule segmentation performance on Breast ultrasound images, reporting metrics such as DICE, Jaccard (JAC), and boundary metrics (HD, ASD).

A research result applies to its stated dataset, split, metric and evaluation configuration. Compare like-for-like settings, preserve the metric's unit and direction, and distinguish paper-reported results from independent reproduction. The best result recorded here is not a claim of exhaustive, current global coverage.

| Scope | Recorded value |
| --- | --- |
| Task | Nodule Segmentation |
| Dataset (including any stated split) | Breast ultrasound images |
| Metric | DICE |
| Unit | PERCENT |
| Direction | Higher is better |
| Results loaded | 7 of 7 |
| Coverage | All results currently returned for this benchmark |

Evaluation settings may differ between results. The original papers and recorded configurations are needed to establish comparability. A shared metric name alone does not establish an identical protocol.

## Metrics

- [DICE](<https://www.sota2.com/research/sota/nodule-segmentation-on-breast-ultrasound-images.md?metric=DICE>): Higher is better; unit: PERCENT.

- [JAC](<https://www.sota2.com/research/sota/nodule-segmentation-on-breast-ultrasound-images.md?metric=JAC>): Higher is better; unit: PERCENT.

- [CON Score](<https://www.sota2.com/research/sota/nodule-segmentation-on-breast-ultrasound-images.md?metric=CON%20Score>): Higher is better; unit: PERCENT.

- [HD](<https://www.sota2.com/research/sota/nodule-segmentation-on-breast-ultrasound-images.md?metric=HD>): Lower is better; unit: SCALAR.

- [ASD](<https://www.sota2.com/research/sota/nodule-segmentation-on-breast-ultrasound-images.md?metric=ASD>): Lower is better; unit: SCALAR.
