Mean and SD of Lesion Kinetic Parameters Estimated by 2T Model With and Without TDC
| Parameter | Without TDC | With TDC | P of paired t test | P of paired signed-rank test |
|---|---|---|---|---|
| td (s) | 0 | 7 ± 5 | 0.0001 | 0.0008 |
| vb (mL/cm3) | 0.027 ± 0.053 | 0.232 ± 0.181 | 0.0002 | 0.0002 |
| K1 (mL/min/cm3) | 0.974 ± 0.814 | 0.331 ± 0.383 | 0.0017 | 0.0002 |
| Ki (mL/min/cm3) | 0.023 ± 0.016 | 0.026 ± 0.017 | 0.0003 | 0.0005 |
| V0 (mL/cm3) | 0.420 ± 0.267 | 0.380 ± 0.221 | 0.0161 | 0.0123 |
Paired t test and Wilcoxon signed-rank test were both used for calculating P value.
