Abstract: A magnetic resonance vessel wall imaging method and device. The method comprises: applying a set pulse sequence into an imaging region, wherein the set pulse sequence comprises, in chronological order, a Delay Alternating with Nutation for Tailored Excitation (DANTE) pulse train, a variable flip angle train of a three-dimensional fast spin echo (SPACE), and a flip-down pulse train (S110); acquiring a magnetic resonance signal generated in the imaging region, and reconstructing a magnetic resonance images of the vessel wall in the imaging region according to the magnetic resonance signal (S120). By adding the flip-down pulse train behind the variable flip angle train of the three-dimensional fast spin echo (SPACE), the cerebrospinal fluid signals of the whole brain can be further suppressed effectively and uniformly, and the DANTE pulse train promotes the vessel wall imaging of the head and neck jointing portion.
