摘要:
In a method and apparatus for magnetic resonance angiography (MRA) a time of flight (TOF) scanning sequence is used that has a first TOF subsequence having at least a saturated zone (T-sat) module and at least an excitation module, with a T-sat module directly followed by at least an excitation module, and a second TOF subsequence that has at least an excitation module and no T-sat module. K-space data, as a first k-space data portion are acquired after each excitation module of the first TOF subsequence, with the first k-space data portion filling the central area of k-space. K-space data, as a second k-space data portion are acquired after each excitation module of the second TOF subsequence, with the said second k-space data portion filling the edge area of k-space. The k-space data are used to reconstruct a magnetic resonance image.
