Photon-Counting CT: A Diagnostic Revolution

The provided sources discuss Photon-Counting Computed Tomography (PCCT), highlighting it as a significant advancement in diagnostic imaging that moves beyond traditional Energy-Integrating Detectors (EIDs). PCCT directly counts individual X-ray photons and measures their energy, leading to superior spatial resolution, elimination of electronic noise, and intrinsic spectral imaging capabilities not found in older CT systems. These technical benefits translate into a wide array of clinical advantages, including enhanced cardiovascular imaging, improved tumor detection for oncology and radiotherapy, clearer neuroimaging, and significant radiation dose reduction for patients. Despite its promise, current limitations such as data management challenges, high costs, and the need for further clinical validation are also addressed, alongside the competitive landscape of manufacturers and recent regulatory approvals that are paving the way for PCCT to become the future standard of care.
