Since the 1990s, hybrid imaging by means of software and hardware image fusion alike allows the intrinsic combination of functional and anatomical image information. This review summarises the state-of-the-art of dual-modality imaging with a focus on clinical applications. We highlight selected areas for potential improvement of combined imaging technologies and new applications. In the second part, we briefly review the background of dual-modality PET-CT imaging, discuss its main applications and attempt to predict technological and methodological improvements of combined PET-CT imaging. After a decade of clinical evaluation, PET-CT will continue to have a significant impact on patient management, mainly in the area of oncological diseases. By adopting more innovative acquisition schemes and data processing PET-CT will become a fast and dose-efficient imaging method and an integral part of state-of-the-art clinical patient management.
