摘要： A method and system determine, with a computer system including one or more processors, a plurality of parameters associated with a volume in an object over time in a series of sequence blocks. In a sequence block in the series of sequence blocks, the plurality of parameters are determined as occurring simultaneously in the volume in the object. At least one parameter of the plurality of parameters varies from the sequence block to another sequence block in the series of sequence blocks, and the plurality of parameters include a contrast related parameter associated with a concentration of a contrast agent in the volume in the object over time in the series of sequence blocks. The computer system generates a signal evolution based on the plurality of parameters of the volume in the object over time in the series of sequence blocks, the signal evolution defining the contrast related parameter over time in the series of sequence blocks.
