Evaluation of PET Super-Resolution performance on the test split of the FDG-PET-CT-Lesions Standard 8 mm FWHM SR×4 dataset, measured using PSNR, SSIM, and NMSE.

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 | PET Super-Resolution |
| Dataset (including any stated split) | FDG-PET-CT-Lesions Standard 8 mm FWHM SR×4 (test) |
| Metric | PSNR (dB) |
| 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 (dB)](<https://www.sota2.com/research/sota/pet-super-resolution-on-fdg-pet-ct-lesions-standard-8-mm-fwhm-sr-4-test.md?metric=PSNR%20(dB)>): Higher is better; unit: SCALAR.

- [SSIM](<https://www.sota2.com/research/sota/pet-super-resolution-on-fdg-pet-ct-lesions-standard-8-mm-fwhm-sr-4-test.md?metric=SSIM>): Higher is better; unit: PERCENT.

- [NMSE](<https://www.sota2.com/research/sota/pet-super-resolution-on-fdg-pet-ct-lesions-standard-8-mm-fwhm-sr-4-test.md?metric=NMSE>): Lower is better; unit: PERCENT.
