摘要：
A system includes a chassis defining a bore, a main magnet to generate a polarizing magnetic field within the bore, a gradient system to apply a gradient magnetic field to the polarizing magnetic field, a radio frequency system to apply an excitation pulse to patient tissue disposed within the bore and to receive signals from the patient tissue, and a computing system to receive the signals from the RF system. The computing system executes program code to control the gradient system and the radio frequency system to acquire a predetermined number of three-dimensional sub-frames from the patient tissue using a T1-weighted radial sampling sequence and without contrast agent, determine a matching one of a plurality of the three-dimensional images reconstructed from respective subsets of the predetermined number of three-dimensional sub-frames, based on a first three-dimensional image reconstructed from a first-acquired one of the predetermined number of three-dimensional sub-frames, and subtract the matching one of the plurality of the three-dimensional images from the first three-dimensional image to generate a second three-dimensional image.
