Abstract: The invention relates to a method for cardiac magnetic resonance imaging. The method comprises the steps of monitoring the ECG of a patient and detecting the occurrence of R-waves (R1, R2, R3) in the ECG, acquiring a plurality of phase encoded MR signals (a1-3, b1-3, c1-3, d1-3, e1-3) per cardiac cycle by subjecting the patient to a sequence of RF pulses and magnetic field gradient pulses, and reconstructing an MR image from at least a part of the MR signals (a1-3, b1-3, C1-3, d1-3, e1-3).

Abstract: A magnetic resonance imaging method is provided in which the magnetic resonance signals are acquired by sampling a selected region in the k-space. The selected region in the k-space is chosen in dependence on the object or structure to be imaged. In particular an anisotropic central sector in the k-space is chosen, its axis being dependent on the spatial orientation of the object or structure to be imaged. The magnetic resonance imaging method in accordance with the invention is particularly suitable for imaging arteries separately from veins in magnetic resonance angiography.

Abstract: A magnetic resonance imaging method is proposed wherein the MR signal acquisition is performed by separate scanning of central (40) and peripheral (70) sectors. Central and peripheral sectors are selected in an individual plane in the k-space and optionally an intermediate sector (50) 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.
