Since their initial description in 1948, Spitz tumours have always been a challenge in the field of dermatopathology and paediatric pathology. Advances in molecular pathology have confirmed they are associated with specific anomalies, mainly gene fusions. They display a wide range of clinical presentations and histological subtypes.

Article Synopsis
  • The study aims to evaluate the effectiveness of Photon-Counting CT (PCCT) compared to Dual-Source CT (DSCT) in reducing radiation dosage while improving the quality of chest CT images.
  • Tests were conducted on phantoms using both CT technologies at various dose levels, with parameters like noise magnitude and detectability of specific lung lesions assessed to measure performance.
  • Results showed that PCCT had significantly lower noise levels and better detectability of lung lesions, with a potential dose reduction of nearly 59% compared to DSCT, indicating PCCT's promise for safer chest imaging in patients.
