PROBLEM TO BE SOLVED: To provide a magnetic resonance device capable of surely checking signal degradation due to a CEST effect, and obtaining a z-spectrum with a reduced side robe.SOLUTION: Scanning means executes n-times of a pulse sequence including a pulse set containing a plurality of RF pulses and a data collection sequence DAQ for collecting data of a site where magnetization exchange of proton occurs. The scanning means causes phases of the RF pulses to cycle so that a phase difference between a phase of the p-th RF pulse and a phase of the p+1-th RF pulse differs for each pulse sequence among the plurality of RF pulses, and obtains the z-spectrum indicating a relation between a signal intensity and a phase difference on the basis of data obtained by repeating the pulse sequence for a plurality of times. |
