For postprocessing dynamic contrast enhanced MRI, automated quantitative transport mapping based on inverting the transport equation is more accurate than traditional Kety’s method and enhancement curve characteristics for differentiating benign from malignant tumors in the breast.

There were no other parameters demonstrating significant difference between malignant and benign lesions.
