Table 3.
Mean and standard deviation of iAUC, Kep and Ktrans.
Number of pixels | iAUC (mm·sec) | Kep (min−1) | Ktrans(min−1) | |
---|---|---|---|---|
Low-active area (LAA) | 4291 | 1.3 ± 3 | 0.5 ± 2 | 0.11 ± 0.5 |
Medium-active area (MAA) | 10333 | 25.6 ± 39 | 11.0 ± 7 | 4.1 ± 3 |
High-active area (HAA) | 7569 | 87.4 ± 109 | 35.9 ± 27 | 19.2 ± 17 |
Mean and standard deviation of iAUC, Kep and Ktrans stratified by active areas for all tumour pixels combined. High-active area had the highest values in all three DCE parameters while low-active area had the lowest values.
