Since the late 1990s, multidetector-row CT has been tried to have wider scan coverage and faster gantry rotation and demonstrated clinical relevance in not only radiology, but also clinical medicine. However, thinner detector collimation and increasing spatial resolution on CT have been limited until the clinical set of ultra-high-resolution CT with energy integrated detector(EID)in 2017. Furthermore, photon counting detector CT(PCDCT)has been started to clinical set in Japan since 2022. Both systems make it possible to examine with thinner detector collimation ≦0.25×0.25×0.25 mm and reconstruct CT images as not only 512×512 matrix, but also 1,024×1,024 or 2,048×2,048 matrix. In this article, we demonstrate basics and clinical potential of UHR-CT for lung cancer as compared with PCDCT.
