PROBLEM TO BE SOLVED: To provide a magnetic resonance apparatus that sets an IR band at an optimal position.SOLUTION: An MR apparatus 100 executes an imaging sequence IS that includes: a selective inversion pulse SIR for flipping magnetization of arterial blood and background tissues and a data acquisition sequence DAQ for acquiring image data from a slab SL including the arterial blood and background tissues. The MR apparatus 100 includes: slab setting means 91 that sets the slab SL and IR band setting means 92 that sets an IR band B and determines an x-way position x2 of a lower end E of the IR band B on the basis of an x-way position x1 of a center C of the slab SL.
