Magnetic resonance imaging apparatus and magnetic resonance imaging method
First Claim
1. A magnetic resonance imaging apparatus comprising:
- a first imaging execution unit configured to, after applying a labeling RF (radio frequency) pulse to blood flowing into a myocardium of a subject, acquire multiple non-contrast MR (magnetic resonance) data for which the time intervals between labeling and acquiring data are different by performing sequential imaging of an imaging area including the myocardium in each segment of a k-space for a given time interval;
an identifying unit configured to identify, on the basis of the acquired multiple MR data, a time interval taken by the labeled blood to reach a given position in the imaging area; and
a second imaging execution unit configured to set the identified time interval as a corresponding parameter of a pulse sequence and, after applying a labeling RF pulse to the blood flowing into the myocardium of the subject, acquire non-contrast MR data by imaging the imaging area including the myocardium.

Abstract
A magnetic resonance imaging apparatus according to an exemplary embodiment includes a first imaging unit, an identifying unit, and a second imaging execution unit. The first imaging execution unit acquires, after applying a labeling RF pulse to blood flowing into the myocardium of a subject, multiple non-contrast MR data for which the time intervals between labeling and acquiring data are different by performing sequential imaging of an imaging area including the myocardium in each segment of a k-space for a given time interval. The identifying unit identifies a time interval taken by the labeled blood to reach a given position in the imaging area. The second imaging execution unit sets the identified time interval and, after applying a labeling RF pulse to the blood flowing into the myocardium of the subject, acquires non-contrast MR data by imaging the imaging area including the myocardium.
