Abstract:
An apparatus for forming a magnetic resonance angiographic image of a human body comprising:means for applying a first plurality of spatially non-selective radio-frequency pulses to a first imaging volume of the human body; means for applying a first plurality of combinations of magnitude of phase-encoding gradients in slice-selective and in-plane directions through the first imaging volume of the human body in conjunction with application of the first plurality of spatially non-selective radio-frequency pulses; means for detecting first magnetic resonance imaging data from the first imaging volume of the human body based upon the first plurality of spatially non-selective radio-frequency pulses and the applied first plurality of combinations of magnitude of phase-encoding gradients; means for applying a second plurality of spatially non-selective radio-frequency pulses to a second imaging volume of the human body; means for applying a second plurality of combinations of magnitude of phase-encoding gradients in slice-selective and in-plane directions through the second imaging volume of the human body in conjunction with application of the second plurality of spatially non-selective radio-frequency pulses; means for detecting second magnetic resonance imaging data from the second imaging volume of the human body based upon the second plurality of spatially non-selective radio-frequency pulses and the applied second plurality of combinations of magnitude of phase-encoding gradients; and means for positioning the human body and acquiring the first and second magnetic resonance imaging data of the first and second imaging volumes without the use of scout images forming the magnetic resonance angiographic image.
