Reproducibility of Metrics Derived from Truncated 30-Minute 18F-FGln Dynamic PET Compared with Full 3-Hour Dataset
| Metric | ICC | Mean difference |
| K1 (mL/min/g) | 0.96 | −0.01 (−0.07, 0.05) |
| k2 (min−1) | 0.63 | −0.03 (−0.20, 0.15) |
| k3 (min−1) | −0.01 | −0.06 (−0.42, 0.30) |
| k4 (min−1) | −0.09 | −0.03 (−0.21, 0.15) |
| VT (mL/cm3) | 0.75 | 0.90 (−0.77, 2.57) |
ICC = intraclass correlation coefficient.
Data in parentheses are lower and upper limits of agreement. Kinetic rate constants were derived using 2C4K model.
