Dorsal C1–2 Spinal Cord Compression After Reduction of Atlantoaxial Posterior Dislocation Associated With Os Odontoideum: A Case Report and Literature Review

Orthopaedic Surgery, EarlyView.
Successful reduction of os odontoideum‐associated atlantoaxial posterior dislocation may not always guarantee adequate C1–2 canal space. In patients with congenital atlas hypoplasia or posterior arch osteophytes, postreduction dorsal cord compression should be anticipated, and C1 posterior arch decompression may be required to prevent neurological ...

Commissioning a single photon counting CT simulator for radiotherapy planning: Methods, challenges, and initial results

Journal of Applied Clinical Medical Physics, Volume 27, Issue 9, September 2026.
Abstract Background Photon counting computed tomography (PCCT) offers distinct advantages over standard energy‐integrated detector (EID) CT by offering energy‐resolved measurements, enhanced spatial resolution, and improved soft‐tissue contrast. While PCCT shows great utility in diagnostic imaging, its application as a radiotherapy simulator has not ...
