Use of population input functions for reduced scan duration whole-body Patlak 18F-FDG PET imaging.

Simulations suggest that scaling of a (possibly incorrect) PIF to IF values seen in whole-body dynamic imaging from 30 to 60 min pi can provide accurate Ki estimates. Consequently, dynamic Patlak imaging protocols may be performed for 30-60 min pi making whole-body Patlak imaging clinically feasible.
