The invention discloses a non-invasive 4D time-resolved dynamic magnetic resonance angiography method. Arterial spin labeling was used to label water molecules as endogenous markers, and multiphase equalization was used to preferentially read pulses to form a dataset. Quantitative tracer kinetic model was established by estimating blood volume, blood flow and mean transit time. The acquired data were used to reconstruct images to provide a set of MR images. The invention can display the blood vessel structure from the viewpoint of improving the spatial resolution, furthermore, the establishment of blood flow model can be optimized from the viewpoint of improving time resolution, and the examination and diagnosis of cerebrovascular diseases by magnetic resonance angiography can be improvedfrom two aspects, and the harmful effects caused by injecting contrast medium and ionizing radiation exposure can be reduced or even eliminated by conventional methods.
