摘要:
The present invention provides a magnetic resonance imaging apparatus and method. The magnetic resonance imaging apparatus comprises a data acquisition unit and an image generating unit. The data acquisition unit configured to acquire magnetic resonance data according to an imaging condition for obtaining a steady state free precession of nuclear magnetic spins in flowing matter in an object by applying plural excitation pulses having a same flip angle with a constant repetition time (TR) and gradient magnetic fields to the object wherein respective zero order moments of gradient magnetic field within the repetition time (TR), gradient magnetic field for slice selection from each application time of the plural excitation pulses till a center time of a corresponding echo, gradient magnetic field for readout from each application time of the plural excitation pulses till a center time of a corresponding echo, gradient magnetic field for slice selection from a center time of each echo till an application time of a following excitation pulse, gradient magnetic field for readout from a center time of each echo till an application time of a following excitation pulse are zero while a first order moment of at least one of gradient magnetic field for slice selection and gradient magnetic field for readout within the repetition time is nonzero. The image generating unit is configured to generate an image of the flowing matter based on the magnetic resonance data.
