Abstract
A magnetic resonance imaging apparatus capable of freely performing the presaturation in a wide-range region over the excited region of the transmiteceive coil and also capable of sufficiently suppressing the blood-flow artifact and the motion artifact to a minimum. The magnetic resonance imaging (MRI) apparatus includes: a static magnetic field generating unit; a gradient magnetic field generating unit where the gradient magnetic field is overlapped to the static magnetic field; a sequencer for executing a desired pulse sequence, in which the pulse sequence includes a main sequence that detects a magnetic resonance signal, and a pre-saturation sequence that saturates magnetization in a biological body under medical examination, prior to execution of the main sequence; first radiofrequency (RF) coil for transmitting a high frequency magnetic field to the biological body according to the main sequence; and second (RF) coil for transmitting a high frequency magnetic field to perform pre-saturation according to the presaturation sequence.
