1. A method of generating a plurality of perfusion images, of a region of interest that are generated from k-space datasets in a magnetic resonance imaging (MRI) system, said method comprising:

  • activating a radio frequency (RF) coil of the MRI system in order to apply a labeling phase of an arterial spin labeling (ASL) pulse sequence to a region of interest;

    generating a tag image of the region of interest with one or more processors of the MRI system, by applying a three-dimensional (3D) radial pulse sequence from the activated RF coil of the MRI system onto the region of interest;

    activating the RF coil of the MRI system in order to apply a control phase of the ASL pulse sequence onto the region of interest, wherein the applied control phase modifies a frequency, a phase, or an amplitude of the ASL pulse sequence;

    generating a control image of the region of interest with the one or more processor of the MRI system, by applying the 3D radial pulse sequence from the activated RF coil onto the region of interest;

    using the one or more processors of the MRI system in order to subtract the generated control image from the generated tag image and in order to generate k-space datasets; and

    using the one or more processors of the MRI system and the generated k-space data sets in order to generate a plurality of perfusion images of the region of interest.
