Computed tomography (CT) has evolved over decades, offering superb morphologic imaging with isotropic resolution at rapid acquisition times. The latest developments in hardware, such as photon-counting and ultrahigh-resolution detectors, together with breakthroughs in software technology have further improved spatial and temporal resolution while steadily reducing radiation exposure. These achievements enable CT for functional imaging and make high-quality imaging more accessible through workflow automation. Radiomics, integrated diagnostics, and data science will further push CT applications beyond their current limits.
