Abstract
In an MRI system, in order to acquire an MR image representing a brain surface anatomy of a head of a subject, a surface coil is disposed near the head of the subject, and a predetermined pulse sequence by a spin echo method, a field echo method, or the like is performed. A view direction is changed for a single slice, and an MR image based on stereoscopic viewing is obtained by a single scan. Regions of interest are set on the brain surface portion on the MR image, and then a predetermined pulse sequence is using an echo time for inhibiting mr signals from fat of the brain surface and using a pulse repetition time for enhancing mr signals from water of the brain surface in order performed to obtain projection data in a direction of depth, thereby allowing accurate grasping of the position of a disease portion.
