Abstract
The invention relates to a method of MR imaging of an object positioned in an examination volume of a MR device (). It is an object of the invention to enable 'silent' ZTE imaging with improved sampling of k-space center. According to the invention, the object () is subjected to an imaging sequence of RF pulses () and switched magnetic field gradients, which imaging sequence is a zero echo time sequence comprising: i) setting a readout magnetic field gradient having a readout direction and a readout strength (G, G); ii) radiating a RF pulse () in the presence of the readout magnetic field gradient; iii) acquiring a FID signal in the presence of the readout magnetic field gradient, wherein the FID signal represents a radial k-space sample (), wherein the acquisition of the FID signal is started at an acquisition time at which a receiver gain of the MR device () has not yet stabilized after the radiation of the RF pulse (); iv) incrementally varying the readout direction; v) sampling a spherical volume in k-space by repeating steps i) through iv) a number of times. Finally, a MR image is reconstructed from the acquired FID signals. Moreover, the invention relates to a MR device and to a computer program for a MR device.
