The invention relates to a magnetic resonance vessel wall imaging method and an apparatus. The method comprising: applying a set of radio frequency pulse sequences to an imaging area, wherein the setof radio frequency pulse sequences includes, in chronological order, a composite double-band delay alternation and a custom excitation nutation A DANTE pulse group, a variable flip angle chain of a three-dimensional fast spin echo SPACE, and a flip down radio frequency pulse chain (S110); acquiring a magnetic resonance signal generated by the imaging area and reconstructing a magnetic resonance signal to obtain the imaging area Magnetic resonance image of blood vessel wall (S120). By further inverting the cerebrospinal fluid signal of the whole brain by increasing the downward flip of the radio frequency pulse chain after the variable flip angle chain of the three-dimensional fast spin echo SPACE, the use of the DANTE pulse group can help the vascular wall at the head-neck joint Imaging.
