1. A magnetic resonance diagnosing apparatus comprising: an imaging unit which images each slice image of a plurality of imaging slices of a subject; a measurement unit which measures a magnetic resonance spectrum of the subject in relation to a measurement slice; a selection unit which selects an imaging slice which is closest to the measurement slice from the plurality of imaging slices; and a creation unit which creates a display image which simultaneously shows the slice image of the selected imaging slice and the spectral image.
