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.
