Dynamic contrast-enhanced imaging of the breast with magnetic resonance

A magnetic resonance imaging method is described which determines the concentration of an intravenous blood marker (Gd-DTPA) in both stationary and flowing solutions. The results indicate that the method should provide accurate (<14%) and rapid (<5 sec) measures of Gd-DTPA concentration in vivo. This method should be useful for improving discrimination between malignant and benign breast lesions and may allow extraction of physiological parameters (e.g., tissue cell fraction and extraction-flow product).
