Abstract: Provided are a method and apparatus for obtaining a magnetic resonance imaging (MRI) image of a subject. Typically, MRI image processing that incorporates fat suppression takes a large amount of time to complete. According to various aspects, image processing that incorporates fat suppression may be postponed until MRI data is repeatedly obtained. By doing so, for example, more MRI data may be obtained during a time period of a heartbeat.
