1. A magnetic resonance imaging apparatus comprising:
- a unit which generates a diffusion weighted image based on a magnetic resonance signal from an object;
a unit which calculates an apparent diffusion coefficient based on the diffusion weighted image; and
a processing unit which subjects the diffusion weighted image to a process of indicating a region having the apparent diffusion coefficient of less than a threshold value with a highlight in contrast with at least one other region of the diffusion weighted image.

Abstract
A magnetic resonance imaging apparatus includes a unit which generates a diffusion weighted image based on a magnetic resonance signal from an object, a unit which calculates an apparent diffusion coefficient based on the diffusion weighted image, and a processing unit which subjects the diffusion weighted image to a process of indicating a region having the apparent diffusion coefficient of less than a threshold value with a highlight in contrast with other region.

9. An image processing apparatus usable with magnetic resonance imaging comprising:
-
a first memory unit which stores a diffusion weighted image of an object; a second memory unit which stores an apparent diffusion coefficient image related to the diffusion weighted image; and a processing unit which subjects the diffusion weighted image to a process of indicating a region having an apparent diffusion coefficient of less than a threshold value with a highlight in contrast with at least one other region of the diffusion weighted image.
