摘要： A magnetic resonance imaging apparatus includes: a sequence controlling unit that, by controlling an execution of a pulse sequence, acquires magnetic resonance (MR) signals corresponding to a plurality of channels in the pulse sequence executed as a series, the MR signals being configured to be arranged into a first region of a k-space at first intervals and into a second region larger than the first region at second intervals larger than the first intervals; an arranging unit that arranges the MR signals corresponding to the channels into the k-space as k-space data; and an image generating unit that generates first-interval k-space data corresponding to the channels based on the second-interval k-space data acquired by executing the pulse sequence and generates a magnetic resonance image based on the generated first-interval k-space data, the first-interval k-space data acquired by executing the pulse sequence, and sensitivity distributions corresponding to the channels.

摘要： Black blood time to inversion (BBTI) tag-on and tag-off images acquired by magnetic resonance imaging (MRI) are analyzed to produce difference magnitude 3D images as a function of time (BBTI values) representing blood perfusion in a region of interest (ROI). Perfusion data of the ROI having values which are different for normal and abnormal myocardial tissues are displayed for plural slices of a 3D image and for plural BBTI values in a single display panel.
