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.
Claims8
An image processing apparatus comprising:
- processing circuitry configured to:
- extract a cerebrospinal fluid (CSF) region including a cerebral ventricle portion region and a cerebral sulcus portion region from a magnetic resonance (MR) image;
- receive an input to specify the cerebral ventricle portion region on the MR image from which the CSF region is extracted;
- and
- extract the cerebral sulcus portion region from the CSF region, based on the specified cerebral ventricle portion region.
An image processing apparatus comprising:
- processing circuitry configured to:
- extract a cerebrospinal fluid (CSF) region including a cerebral ventricle portion region and a cerebral sulcus portion region from a magnetic resonance (MR) image;
- identify the cerebral ventricle portion region on the MR image from which the CSF region is extracted;
- and
- extract the cerebral sulcus portion region from the CSF region, based on the identified cerebral ventricle portion region.
