One the most important aspects of PET imaging is the ability to quantify the uptake of tracer in a specific tissue, and the implementation of Standard Uptake Values (SUV) based on static images was a key milestone to facilitate the utilization of semi- quantitative metrics in the clinic. However, PET tracer distribution — a dynamic process altered by a number of factors specific to each organ and region of interest — cannot always be accurately accounted for with SUV.
FlowMotion Multiparametric PET Suite is completely automated and integrated into the PET/CT workflow, allowing users to obtain images of SUV, metabolic glucose rate (Ki) and distribution volume (DV) all at once for more reproducible images and thereby more efficient information for planning and therapy strategy.
FlowMotion enables whole-body dynamic acquisitions
Dynamic imaging has been limited to a single-bed position, with the organ of interest positioned in the center of the detectors. With FlowMotion, you can obtain whole-body dynamic images by continually moving the bed through the gantry in a bi-directional motion along the entire body so you can visualize the tracer distribution over time.
Key benefits of FlowMotion Multiparametric PET Suite
- Fully automated solution obtains whole-body images of metabolic glucose rate and distribution volume, in addition to SUV images
- Flexible acquisition protocols enable use in clinical research settings
- Reduces the variability of quantitative measurements due to differences in uptake time, patient body size and blood glucose levels, leading to better characterization of tracer uptake compared to SUV alone
- Provides additional information to evaluate therapy effectiveness based on metabolic glucose rates compared to SUV alone
