Additionally it has been advised which the variability when there is a change in SUV may be a log-usual distribution, click here for info instead of a normal distribution49.
Nevertheless, in apply there are plenty of resources of bias and variance which might be introduced inside the measurement of FDG uptake in tumors and in addition from the conversion in the graphic rely info to SUVs.

Recommendations are delivered for very best practices in improving upon SUV accuracy.
So, which process is best for yourself? It relies on your movement by means of utilization and Room prerequisites.
