A system and method for imaging a desired region of the circulatory system uses the subtraction of data from two acquisitions using substantially different RF pulses and/or pulse sequence timing parameters. In one or both data sets, the longitudinal magnetization of spins within a selected imaging volume has been altered by the application of one or more RF preparatory (prep) pulses. The prep is applied in such a way that subtraction eliminates signals from static background spins, such as fat, while maintaining the signal intensity of intravascular spins.
