Abstract EN
Currently, kinetic analyses using dynamic positron emission tomography (PET) experience very limited use despite their potential for improving quantitative accuracy in several clinical and research applications.
For targeted volume applications, such as radiation treatment planning, treatment monitoring, and cerebral metabolic studies, the key to implementation of these methods is the determination of an arterial input function, which can include time-consuming analysis of blood samples for metabolite correction.
Targeted kinetic applications would become practical for the clinic if blood sampling and metabolite correction could be avoided.
To this end, we developed a novel method (Patlak-P) of generating parametric maps that is identical to Patlak Ki (within a global scalar multiple) but does not require the determination of the arterial input function or metabolite correction.
In this initial study, we show that Patlak-P (a) mimics Patlak Ki images in terms of visual assessment and target-to-background (TB) ratios of regions of elevated uptake, (b) has higher visual contrast and (generally) better image quality than SUV, and (c) may have an important role in improving radiotherapy planning, therapy monitoring, and neurometabolism studies.
