Magnetic resonance imaging apparatus and breath-holding imaging method

摘要

In order to make it possible to set the optimal breath-holding imaging conditions according to the subject without extension of an imaging time or the sacrifice of image quality, one scan is divided into one or more breath-holding measurements and free-breathing measurements on the basis of the imaging conditions of a breath-holding measurement, which are input and set according to the subject, and a region of the k space measured in the breath-holding measurement is controlled. Preferably, in the breath-holding measurement, low-frequency data of the k space is measured. Moreover, preferably, imaging conditions of the breath-holding measurement include the number of times of breath holding or a breath-holding time, and the operator can set any of these values.

主权项

1. A magnetic resonance imaging apparatus comprising:
a measurement controller which acquires k space data by a breath-holding measurement to measure some data of the k space during a breath-holding period of a subject; and a breath-holding imaging condition input unit that receives an input of imaging conditions of the breath-holding measurement, wherein the measurement controller divides one scan into one or more breath-holding measurements and free-breathing measurements according to the imaging conditions including at least one of a breath-holding time and the number of times of breath-holding of the breath-holding measurement and controls a region of the k space measured in the breath-holding measurement.
