Abstract: A magnetic resonance imaging apparatus according to an embodiment includes processing circuitry. The processing circuitry sets an imaging region and a labeling region based on at least a blood vessel structure, the imaging region being a region of a matrix of a plurality of divided voxels including different blood vessel regions, respectively, the labeling region being a region to which a labeling pulse for labeling blood flowing into the imaging region is applied. The processing circuitry acquires data of the imaging region by applying the labeling pulse to the labeling region by using an arterial spin labeling (ASL) method. The processing circuitry generates an image based on the data. The processing circuitry determines anomaly of the blood vessel regions by comparing signal values of the voxels included in the image.

Abstract: A medical image processing apparatus according to a present embodiment includes processing circuitry. The processing circuitry is configured to: acquire a subject image relating to a subject; acquire a standard image indicating a morphological structure of a human body and sections of a morphological structure from a memory which stores each standard image in association with sections of a morphological structure; set a comparison target portion of the subject image based on the subject image; set a comparison target portion of the standard image based on a comparison between the subject image and the standard image; specify a section in the comparison target portion of the subject image based on a comparison between the comparison target portion of the subject image and the comparison target portion of the standard image; and output the subject image and the section in association with each other.

Abstract: In one embodiment, an MRI apparatus includes a memory storing a predetermined program and processing circuitry. The processing circuitry is configured, by executing the predetermined program, to generate a first image having a first phase affected by susceptibility, generate a second image having a second phase affected by both of the susceptibility and flow, and distinguish difference in susceptibility or flow for a pixel of a third image by using the first phase and the second phase or by using a value calculated from the first phase and a value calculated from the first phase, the third image having regions which are substantially same in contrast.

Abstract: A magnetic resonance imaging apparatus according to an embodiment includes a sequence controller and a storage unit. The sequence controller acquires magnetic resonance signals of a target imaging part including cerebrospinal fluid flowing therein of a subject in a condition where a supply of oxygen is receivable, at a plurality of time phases in an oxygen inhalation process of the subject. The storage unit stores therein the magnetic resonance signals acquired at the time phases.
