A study published in Pediatric Radiology led by Narum, Yu, and McCollough demonstrated that high‑pitch cardiac CT using photon‑counting detectors achieves equivalent contrast‑to‑noise ratio (CNR) at lower radiation doses. The investigators compared photon‑counting CT protocols and concluded the technology can reduce pediatric cardiac imaging exposure without sacrificing image quality. The paper provides imaging teams a data‑driven protocol to adopt photon‑counting detectors in high‑pitch cardiac scans. For clinicians and imaging manufacturers, the result signals a practical pathway to reduce cumulative radiation in vulnerable patient populations while maintaining diagnostic performance.
