Comparing the Biograph Vision 600 and the Biograph Vision.X PET/CT scanners

Is this trial a fit for you?

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This project collects clinical PET/CT images acquired on two Siemens Biograph systems to compare image quality and diagnostic performance. Adults referred for PET/CT because of cancer or suspected/known Alzheimer disease will be enrolled if they can give consent and lie still for the scan. Images from the Vision 600 and the newer Vision.X system will be reviewed and compared by readers using standardized image-quality and diagnostic criteria. The work is performed at the University Hospitals of Geneva and focuses on initial clinical experience with the Vision.X hardware.
