Evaluation-design effects and reference-CT-defined HU-class errors in brain MRI-to-CT synthesis on SynthRAD2023: a technical note.

To quantify how evaluation design affects brain MRI-to-CT synthesis performance, we analyzed 180 MRI/CT pairs from three centers in the SynthRAD2023 Task 1 dataset. A lightweight 2D U-Net was trained with a common validation-based stopping rule under slice-random, patient-random, center-stratified size-matched patient-...
