Abstract
A method for detecting lesion tissue using contrast agent MRI includes receiving scanner settings; receiving MR parameters for lesion tissue with or without contrast agent; and simulating relationships between an image quality metric and imaging parameters. The method includes selecting a first set of imaging parameters to optimize an image quality metric of a first image acquired before contrast agent administration; selecting a second set of imaging parameters to optimize a lesion enhancement metric of a second image acquired after contrast agent administration; and selecting an image acquisition time for the second image to maximize the lesion enhancement metric. The method includes acquiring the first and second images using the selected first and second sets of imaging parameters, respectively; and generating a combined image from the first and second images.
