Method of MR imaging of an object placed in an examination volume of a MR device , the method comprising: - subjecting the object to an imaging sequence of at least one RF pulse and switched magnetic field gradients, - acquiring MR signals according to a stack-of-stars scheme, wherein the MR signals are acquired by sampling spokes formed by radial k-space profiles (S1-S12) at a number of different angular positions and from a number of a central and peripheral parallel slices (21-27) arranged at different positions along a slice direction, wherein - a central set of spokes is sampled at different orientations from the central slice, - additional sets of spokes are sampled from the central and outward peripheral slices, the additonal sets of spokes having respective mutually rotated different orientations, - wherein a radial density of the k-space profiles (S1-S12) (i) varies as a function of position of the slices and the radial density is higher at more central k-space positions and lower at positions in a more peripheral k-space region and (ii) generates Nyquist-circles in each of the central and peripheral slices forming a Nyquist-ellipsoid in 3D k-space of growing size with additional sets of spokes sampled and within which an at least full sampling of k-space is achieved, - the k-space profiles (S1-S12) are acquired at a higher temporal density from slices at more central k-space positions than from slices at more peripheral k-space positions and - a time series of MR images is reconstructed from the MR signals, wherein respective MR images of the time series are reconstructed using only the k-space profiles within the Nyquist ellipsoid acquired at the respectively closest time points in combination with the k-space profiles acquired from the peripheral k-space regions which are sampled at more distant time points. - subjecting the object to an imaging sequence of at least one RF pulse and switched magnetic field gradients, - acquiring MR signals according to a stack-of-stars scheme, wherein the MR signals are acquired by sampling spokes formed by radial k-space profiles (S1-S12) at a number of different angular positions and from a number of a central and peripheral parallel slices (21-27) arranged at different positions along a slice direction, wherein - a central set of spokes is sampled at different orientations from the central slice, - additional sets of spokes are sampled from the central and outward peripheral slices, the additonal sets of spokes having respective mutually rotated different orientations, - wherein a radial density of the k-space profiles (S1-S12) (i) varies as a function of position of the slices and the radial density is higher at more central k-space positions and lower at positions in a more peripheral k-space region and (ii) generates Nyquist-circles in each of the central and peripheral slices forming a Nyquist-ellipsoid in 3D k-space of growing size with additional sets of spokes sampled and within which an at least full sampling of k-space is achieved, - the k-space profiles (S1-S12) are acquired at a higher temporal density from slices at more central k-space positions than from slices at more peripheral k-space positions and - a time series of MR images is reconstructed from the MR signals, wherein respective MR images of the time series are reconstructed using only the k-space profiles within the Nyquist ellipsoid acquired at the respectively closest time points in combination with the k-space profiles acquired from the peripheral k-space regions which are sampled at more distant time points. <EOS>
