Evaluation of scanner harmonization performance comparing Skyra and Prisma acquisitions with a b-value of 2000 s/mm², assessed using Fractional Anisotropy (FA), Mean Diffusivity (MD), and Generalized Fractional Anisotropy (GFA).

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 | Scanner Harmonization |
| Dataset (including any stated split) | Skyra → Prisma b = 2000 s/mm² |
| Metric | Fractional Anisotropy (FA) |
| Unit | SCALAR |
| Direction | Higher is better |
| Results loaded | 5 of 5 |
| 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.
