Abstract
An image processing apparatus according to an embodiment includes a specifying unit and a deriving unit. The specifying unit specifies a fluid region in a plurality of magnetic resonance images that are acquired by applying a labeling pulse to a label region and that are mutually related. The deriving unit derives an index indicating dynamics of a fluid on the basis of the specified fluid region.

17. A magnetic resonance imaging apparatus comprising:
-
an acquiring unit configured to set a label region where cerebrospinal fluid (CSF) is flowing, within an imaging region, and to acquire images corresponding to a plurality of time phases along a time series by applying a labeling pulse to the label region; a specifying unit configured to specify a CSF region in the images corresponding to the plurality of time phases; and a deriving unit configured to derive an index indicating dynamics of a CSF on a basis of the specified CSF region, wherein the acquiring unit limits a range of imaging timing with which the images are acquired, by using a time at which longitudinal magnetization of the CSF become zero as a reference. - View Dependent Claims (18, 19, 20)
