PROBLEM TO BE SOLVED: To provide a magnetic resonance diagnostic apparatus capable of executing three-dimensional MR angiography, while sufficiently maintaining a fat control effect, without much degrading MR signals from the bloodstream. SOLUTION: A magnetic resonance diagnostic apparatus comprises gradient magnetic field power sources 7 to 9 which can apply a gradient magnetic field on a static magnetic field, RF transducing sections 5 and 6 which can transmit RF pulses to a subject in the static magnetic field and receive MR signals from the subject, and a sequencer 10 which controls the gradient magnetic field power sources and the RF transducing sections. The sequencer is designed to control the gradient magnetic power sources and the RF transducing sections according to a prescribed pulse sequence. The pulse sequence includes a prepulse having an additional effect and an imaging sequence for collecting MR signals from the three-dimensional region of the subject according to the 3DFT law. The prepulse is applied so as to bring an additional effect only on part of the region including areas in and around the origin of a three-dimensional k space under the 3DFT law.
