| titleOfInvention | Method for displaying blood vessels by means of an MR device |
| abstract | The invention relates to a method for vessel representation by means of a magnetic resonance apparatus based on the time-of-flight (TOF) technique, wherein a magnetic field is applied to an imaging volume of a subject and an inflow volume from which liquid enters the imaging volume. In a further step, the imaging volume is excited by HF pulses which satisfy a magnetization transfer function and a fat saturation function during the application of the magnetic field. The HF pulses have a frequency distribution whose frequency is substantially lower than the center frequency of the water in the imaging volume and which includes the fat frequency in the imaging volume. Furthermore, the magnetic field has a magnetic field distribution which has an apex region in the imaging volume which is substantially free of spatial gradients and a higher spatial gradient in the inflow volume, wherein the center frequency of the water in the inflow volume is shifted in the direction of the higher frequency, whereby it is no longer influenced by the HF pulse. |
