Design outcomes

Primary

Measure	Time frame
The quantitative accuracy will be assessed by evaluating the relationship between the standardized uptake values (SUVs) of fxPET and those of whole-body PET/CT.	—

Secondary

Measure	Time frame
The image quality of fxPET images will be analysed visually by two board-certified nuclear medicine physicians by means of a 4-point grading scale.	—
