Abstract:
1. A magnetic resonant imaging method for raking an image of a desired imaging region of a subject by using a magnetic resonant imaging apparatus, the method comprising the steps of: (a) a physical-movement information acquiring step of acquiring physical-movement information of the subject; (b) a longitudinal-magnetization regulating step of performing a first pulse sequence, for making a longitudinal-magnetization in a region including the desired imaging region be a desired state, synchronously with the physical-movement information; (c) a measuring step of subsequently performing a second pulse sequence, for measuring at least one echo signal to take an image of the desired imaging region, synchronously with the physical-movement information; and (d) a reconstructing step of reconstructing and displaying the image by using the at least one echo signal measured in the measuring step (c), wherein the first pulse sequence has a regulation pulse that excites, to a predetermined angle, the longitudinal-magnetization in the region including the desired imaging region, and the first pulse sequence is performed at least two times during a predetermined number of heartbeats, said predetermined number being at least two, the second pulse sequence having an inversion pulse that inverts, by 180 degrees, the longitudinal-magnetization in the desired imaging region.
