A dynamic MRA study of a subject is performed using a 3D fast gradient- recalled echo pulse sequence that employs a non-selective RF excitation pulse. The frame rate of the resulting series of reconstructed images is increased by sampling a central region of k- space at a higher rate than the peripheral regions of k-space. The acquisition is gated using a cardiac trigger signal and the central region of k-space is acquired during diastole and the peripheral regions of k-space are acquired during systole. Image frames are reconstructed at each sampling of the central k- space region using the temporally nearest samples from the peripheral k- space regions. Two of the image frames are subtracted to form an MR angiogram.
