Abstract
A magnetic resonance imaging apparatus according to the present embodiment includes sequence control circuitry and processing circuitry. The sequence control circuitry controls execution of a pulse sequence which includes a first segment and a second segment being provided prior to the first segment. The first segment is where signal acquisition is performed. The second segment is where longitudinal magnetization and transverse magnetization are reduced by applying a plurality of RF magnetic field pulses while changing a magnitude and/or a phase thereof and a plurality of spoiler gradient field pulses.

A magnetic resonance imaging apparatus comprising:
- sequence control circuitry configured to control execution of a pulse sequence which includes a first segment and a second segment being provided prior to the first segment, the first segment being where signal acquisition is performed, the second segment being where an orientation of each proton within an imaging area being three-dimensionally dispersed and macroscopic longitudinal magnetization and transverse magnetization are reduced to substantially zero by applying a plurality of RF magnetic field pulses while changing a magnitude and/or a phase thereof and a plurality of spoiler gradient field pulses;
- and
- processing circuitry configured to generate an image based on signals acquired by the pulse sequence.
