Abstract
A magnetic resonance imaging method is proposed wherein the MR signal acquisition is performed by separate scanning of central ( ) and peripheral ( ) sectors. Central and peripheral sectors are selected in an individual plane in the k-space and optionally an intermediate sector ( ) between the peripheral and central sectors is also selected. The center (O) in the k-space in the individual plane at issue is situated within the central sector. The scanning of the k-space commences outside the center of the k-space and before or during increasing contrast. Preferably, the scanning is timed such that the center of the k-space is reached at maximum contrast (MR angiography) or at the value zero of the longitudinal magnetization (MR inversion recovery). The central sector is advantageously scanned in a stochastic order. The peripheral sector may be scanned along a spiral-shaped trajectory, radial trajectories or along high-low ordered lines.
