Evaluation of MRI synthesis models performing Pre-contrast to Contrast-enhanced (Pre to CA) image generation using the test split of the LLD-MMRI 2023 dataset, assessed via image fidelity metrics like PSNR, SSIM, and LPIPS.

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 | MRI Synthesis (Pre to CA) |
| Dataset (including any stated split) | LLD-MMRI 2023 (test) |
| Metric | PSNR |
| Unit | SCALAR |
| Direction | Higher is better |
| Results loaded | 8 of 8 |
| 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

- [PSNR](<https://www.sota2.com/research/sota/mri-synthesis-pre-to-ca-on-lld-mmri-2023-test.md?metric=PSNR>): Higher is better; unit: SCALAR.

- [SSIM](<https://www.sota2.com/research/sota/mri-synthesis-pre-to-ca-on-lld-mmri-2023-test.md?metric=SSIM>): Higher is better; unit: PERCENT.

- [LPIPS](<https://www.sota2.com/research/sota/mri-synthesis-pre-to-ca-on-lld-mmri-2023-test.md?metric=LPIPS>): Lower is better; unit: SCALAR.
