An ideal breast MRI protocol might include high spatial and high temporal resolution images acquired following a single contrast agent injection. Here we present an acquisition strategy to acquire both for clinical reporting and tracer kinetic analysis. The approach was evaluated using simulations and tested through application in patients undergoing neoadjuvant chemotherapy. Radiologists could adapt similar protocol strategies to examine the physiological characteristics of tumors and their associated changes during treatment without significantly compromising the data used for clinical reporting.
