PROBLEM TO BE SOLVED: To provide a magnetic resonance imaging apparatus capable of suppressing signals from a predetermined area in an imaging area with few excitation pulses.SOLUTION: In the imaging area including a subject, two partially overlapping areas S11 and S12 are determined. At the time, a signal suppression area is included in the non-overlapping area of the two areas, and a signal read area is included in the overlapping area of the two areas. Then, by applying an inversion pulse to each of the two areas, magnetic resonance signals are suppressed by inverting longitudinal magnetization of a spin once for the non-overlapping area, and the longitudinal magnetization of a spin is inverted twice to be practically returned to the original for the overlapping area W1. Thereafter, at the point of time when the longitudinal magnetization of the excited spin in the non-overlapping area becomes a null point, a pulse sequence for collecting signals is started, and the magnetic resonance signals from the overlapping area W1 are collected.COPYRIGHT: (C)2012,JPO&INPIT【課題】撮像領域における所定領域からの信号の抑制を少ない励起パルスで行うことができる磁気共鳴イメージング装置を提供する。【解決手段】被検体を含む撮像領域において、一部が重複する2つの領域S11,S12を定める。この際、上記2つの領域の非重複領域に信号抑制領域が含まれ、上記2つの領域の重複領域に信号読取領域が含まれるようにする。次に、上記2つの領域にインバージョンパルスをそれぞれ印加することにより、上記非重複領域については、スピンの縦磁化を1回反転させて磁気共鳴信号を抑制し、上記重複領域W1については、スピンの縦磁化を2回反転させて実質的に元に戻す。その後、上記非重複領域における励起されたスピンの縦磁化がヌルポイントになった時点で信号収集用パルスシーケンスを開始し、上記重複領域W1からの磁気共鳴信号を収集する。【選択図】図2
