Results

In benign tumours, significant differences existed in MAX Conc. (p=0.000), AUC-TC (p=0.000), MAX Slope (p=0.000), Ktrans (p=0.000), Kep (p=0.000) and Ve (p=0.001) between the lesion and control groups. In malignant tumours, significant differences existed in TTP (p=0.000), MAX Conc. (p=0.000), AUC-TC (p=0.000), MAX Slope (p=0.000), Ktrans (p=0.000), Kep (p=0.000), and Ve (p=0.000) between the lesion and the control groups. There were significant differences in MAX Conc. (p=0.000), AUC-TC (p=0.000), MAX Slope (p=0.000), Ktrans (p=0.000), and Kep (p=0.003) between benign soft tissue tumours and malignant soft tissue tumours. The AUC of the ROC curve demonstrated the diagnostic ability of  MAX Conc. (0.849), AUC-TC (0.831), MAX Slope (0.847), Ktrans (0.836) and Kep (0.778). No semi-quantitative or quantitative parameter showed a significant difference between the benign control and malignant control group.
