ABSTRACT:
A magnetic resonance imaging method and system utilizing a magnetization transfer contrast pulse that includes executing a first sequence including the application of the magnetization transfer contrast pulse to an examinee and executing a second sequence for acquiring a magnetic resonance angiography image data related to a predetermined imaging plane. The first sequence further includes the step of applying a slice gradient magnetic field for spatially selectively exciting a predetermined magnetization transfer contrast excitation plane at substantially the same timing as that of the magnetization transfer contrast pulse. A predetermined gradient magnetic field is applied by a gradient magnetic field application means in a manner superimposing upon a predetermined static magnetic field. An RF transmitting/receiving means is arranged for transmitting an RF pulse to an examinee and receiving a magnetic resonance signal from the examinee. The gradient magnetic field application means and the RF transmitting/receiving means is controlled by a control means in accordance with the predetermined pulse sequence.
