RIQE: a NIQE-style reference model for Computed Tomography

The paper introduces RIQE, a reference-free image quality evaluator for computed tomography that mirrors the NIQE framework used for photographs. Trained on 3,792 full‑dose CT slices from 158 patients, RIQE consistently ranks reduced‑dose reconstructions lower than their full‑dose counterparts and correctly identifies increased noise levels, but its preferences for filtered images do not align with lesion visibility. The authors caution that RIQE should not be the sole metric for selecting or tuning denoising algorithms.
