Abstract
A magnetic resonance imaging apparatus according to an embodiment includes an execution unit and a generation unit. The execution unit executes first data collection after a predetermined inversion time elapses from a time when a labeling pulse is applied to a fluid flowing into an imaging region of a subject and a second data collection without application of the labeling pulse. The generation unit generates a differential image by using the first data and the second data. Here, the generation unit generates the differential image by a different differential method according to a relationship between the inversion time and a longitudinal relaxation time of the fluid.

A magnetic resonance imaging apparatus comprising:
- execution circuitry configured to execute first data collection after a predetermined inversion time elapses from a time when a labeling pulse is applied to a fluid flowing into an imaging region of a subject and second data collection without application of the labeling pulse;
- and
- generation circuitry configured to generate a differential image by using the first data and the second data,
- wherein the generation circuitry is configured to generate the differential image by (i) a first differential method when the inversion time and a longitudinal relaxation time of the fluid have a first relationship, and (ii) a second differential method, differing from the first differential method, when the inversion time and a longitudinal relaxation time of the fluid have a second relationship differing from the first relationship.
A magnetic resonance imaging (MRI) method comprising:
- using an MRI system to effect
- collecting first MRI data after a predetermined inversion time elapses from a time when a labeling pulse is applied to a fluid flowing into an imaging region of a subject and collecting second MRI data without application of the labeling pulse;
- and
- generating a differential image by using the first MRI data and the second MRI data,
- wherein the differential image is generated by (i) a first differential method when the inversion time and a longitudinal relaxation time of the fluid have a first relationship, and (ii) a second differential method, differing from the first differential method, when the inversion time and a longitudinal relaxation time of the fluid have a second relationship differing from the first relationship.
