Provided is a magnetic resonance imaging (MRI) apparatus including: a controller configured to determine a first slice and a second slice so that a difference between a slice number of the first slice of an object and a slice number of the second slice of the object is a predetermined interval value; and a radio frequency (RF) coil configured to transmit a preparation pulse signal including a frequency component enabling the first slice to be excited and transmit an RF signal including a plurality of frequency components so that both the first slice and the second slice are excited.
