PROBLEM TO BE SOLVED: To acquire an image with few FID (Free Induction Decay) artifacts without increasing the strength of a spoiler gradient magnetic field to a large extent.SOLUTION: According to a magnetic resonance imaging apparatus according to an embodiment, an RF (Radio Frequency) pulse applying unit applies to a subject a flip pulse for exciting spin of nuclei inside a subject body, and a flop pulse for refocusing the phase of the spin. A gradient magnetic-field applying unit applies a spoiler gradient magnetic field onto the subject after the flop pulse is applied, and applies a rewind gradient magnetic field before applying the flop pulse. When performing imaging by a three-dimensional high speed spin echo method, a control unit executes a pulse sequence of controlling the gradient magnetic-field applying unit so as to keep each of the strengths of the spoiler gradient magnetic field and the rewind gradient magnetic field at respective predetermined values or higher with respect to each of a plurality of slice encodings.
