Abstract:
In a method and magnetic resonance apparatus for image acquisition using a magnetic resonance sequence in which k-space corresponding to the imaging area is scanned, a first region of k-space, which does not include the center of k-space, is scanned radially along a number of spokes emanating from the k-space center, and at least two phase coding gradients are completely ramped up before the excitation pulse. A second central region of k-space, which remains without the first region, is scanned in a Cartesian manner. For contrast increase a pre-pulse is provided before a predetermined number of individual measurements. The number of spokes is selected so a measurement point nearest to the k-space center is measured at a predetermined point in time after the pre-pulse, which is optimal for signal-to-noise ratio and/or contrast.
