Findings

This is an F-DOPA PET/CT. The scan was performed with very low radiotracer dose (101MBq) in 20min (5 4min-Steps). It showed a single liver metastasis.

Conclusion

For expensive radiotracers like F-DOPA, scans can be performed with preserved image quality using very low injected dose for a total duration that is very acceptable for the patient. 

Discovery IQ’s high sensitivity thus enables wider access to these expensive radiotracers, as well as routine use with excellent image quality. 

The reduction of the effective dose is also an important consequence here.
