A method for the generation of said angiographic magnetic resonance images

摘要

The invention relates to a method for generating a series of temporally successive angiographic magnetic resonance images of an examination zone. In the method, a sequence with a predetermined number (n) of tilt angles (α) is fixed. The first tilt angle (α₁) at the beginning of the sequence is smaller than the last tilt angle (α_N) at the end of the sequence, and any desired tilt angle (α_i) is substantially greater than or equal to the in the sequence preceding tilt angle (α_{i - 1}). First and second collects magnetic resonance data (a, b), by means of detecting a predetermined number (na, nb) of partial segments of a to the first and second collects magnetic resonance data (a, b) is determined which are associated with a k - space. Each segment is in each case via a first or second time interval detected and has a sequence of components (a_ij, B_ij) on. Each component (a_ij, B_ij) if, according to a gradient echo method with an angle of inclination (α_i) is detected, which on one of the component (a_ij, B_ij) corresponding position (i) is present in the sequence of the angle of tilt. At the beginning of the first time intervals has a liquid flowing into the examination zone, a first predetermined spin - marking and at the beginning of the second time intervals a to this end different second predetermined spin - marking on. The sequence of successive angiographic magnetic resonance images, by combining the first and second collects magnetic resonance data (a, b) is generated.
