Indication for PET-CT

PET/CT has the potential to become the new high-end diagnostic imaging modality for various indications. Today PET/CT is most widely used in oncological imaging and detection of inf lammatory disease but also for selected questions in neurology, cardiac and vascular imaging. New developments, especially in molecular imaging can further increase the spectrum of PET/CT indications. Availability and the high costs of the PET/CT examination are still limiting the use of PET/CT to certain centers. The comparatively high radiation exposure of whole body PET/CT scanning requires a very responsible establishment of indications for PET/CT examinations.
