This brief report aimed to show the utility of photon-counting technology alongside standard cranial imaging protocols for visualizing shunt valves in a patient’s cranial computed tomography scan. Photon-counting CT scans with cranial protocols were retrospectively surveyed and four types of shunt valves were encountered: proGAV 2.0^(®), M.blue^(®), Codman Certas^(®), and proSA^(®). These scans were compared with those obtained from non-photon-counting scanners at different time points for …
