  • Patent number: 9360539
    Abstract: A system for perfusion and diffusion MR imaging of a portion of patient anatomy includes an RF (Radio Frequency) signal generator for generating RF excitation pulses in anatomy and enabling subsequent acquisition of associated RF echo data. A magnetic field gradient generator generates anatomical volume select magnetic field gradients for phase encoding and readout RF data acquisition in a three dimensional (3D) anatomical volume. The RF signal generator and the gradient generator acquire within a single MR imaging scan, perfusion image data of the 3D volume, at least partially in the presence of contrast agent, and diffusion image data of the 3D volume.
    Type: Grant

  • Patent number: 9140771
    Abstract: In one aspect of the disclosure, an MRI-based system includes an MRI scanner having a first axis and a first plane perpendicular to the first axis, a pulse sequence module configured to provide a 3D pulse sequence to the MRI scanner, and a control module configured to instruct the MRI scanner to conduct radial k-space samples having N second planes that each are perpendicular to the first plane and through which the first axis passes, N being an integer greater than 1. The 3D pulse sequence instructs the MRI scanner to a radio-frequency (RF) pulse, conduct a gradient readout in the first plane, and conduct a gradient readout in one of the N second planes.
