Initial maximum slope of enhancement as derived from ultrafast TWIST images acquired during contrast inflow provides a strong discriminator between benign and malignant disease that outperforms classic 3-timepoint analysis. By using a fixed grid of relative enhancement versus time curve types can be defined that can be easily implemented in current radiological practice.
