window (e.g., to better categorize cohorts or reach SUVR steady state) should be made with caution as noise for some scans started increasing at 50 minutes. The regional clearance rate k2 might be explored as an additional metric and could be esimtated from dynamic 80-100 (or 75-105) minute scans. Further dynamic studies are planned and additional evaluation of kinetic modeling methodologies is warranted.
