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