To simultaneously acquire an MRA image and plural images by which structures of tissues other than a blood vessel can be recognized, without performing imaging of the MRA image, and to shorten a time required for MR examination.SOLUTION: Two or more kinds of physical value dependent images acquired from a nuclear magnetic resonance signal measured at plural imaging conditions according to a prescribed pulse sequence, are combined using a prescribed combination function and a combination parameter. At this time, plural divided areas are set in the physical value dependent images, and for each divided area, by using reference data of two or more kinds of physical value dependent images, a combination parameter satisfying a condition in which a difference between a pixel value of a specific tissue and a pixel value of a tissue other than the specific tissue becomes larger, is determined for the two or more kinds of physical value dependent images, and the combination parameter is used for combination of the two or more kinds of images.SELECTED DRAWING: Figure 2【課題】 ＭＲＡ画像用の撮像を行うことなく、ＭＲＡ画像と、血管以外の組織の構造が把握できる複数の画像を同時に取得し、ＭＲ検査の時間を短縮する。【解決手段】 所定のパルスシーケンスに従って複数の撮像条件で計測した核磁気共鳴信号から得た２種類以上の物性値依存画像を、所定の合成関数と合成パラメータとを用いて合成する。その際、物性値依存画像に複数の分割領域を設定し、分割領域ごとに、２種類以上の物性値依存画像の標準データを用いて、実測した前記２種類以上の物性値依存画像について、特定組織の画素値と特定組織以外の組織の画素値との差が大きくなる条件を満たす合成パラメータを決定し、前記２種類以上の画像の合成に用いる。【選択図】図２
