Detailed visualization of the cribriform plate is challenging due to its intricate structure. This study investigates how computed tomography (CT) with a novel photon counting (PC) detector enhance compared traditionally used energy-integrated detectors in patients. A total 40 patients were included retrospective analysis, half them undergoing PC CT (Naeotom Alpha Siemens Healthineers, Forchheim, Germany) and other scans using an (Somatom Sensation 64, Siemens, which was visualized temporal bone protocol. Both groups evaluated for signal-to-noise ratio, radiation dose, imaging quality whole scan overall, and, separately, clarity volume rendering reconstructions. Two independent observers conducted qualitative analysis Likert scale. The results consistently demonstrated excellent scanner, surpassing traditional technology. provided by allowed precise anatomical assessment on multiplanar reconstructions reduced dose (by approximately 50% per slice) higher ratio 75%). In conclusion, photon-counting technology provides possibility better adult enhanced could be utilized skull base-associated pathologies, such as cerebrospinal fluid leaks, visualize more reliably treatment.
