Embodiment Construction

[0012] exist figure 1 The dark areas in the diffusion image of , represent dead brain regions of the patient that will most likely no longer be salvaged. in accordance with figure 2 The identifiable area of ​​the perfusion image of 1 has a dead area 1 that will no longer heal if this patient is not treated. by putting figure 2 The perfusion image with figure 1 By overlaying the diffusion-weighted images, doctors can identify the status of damaged brain regions at a glance and better judge where key locations are and which parts can actually be saved.

[0013] In practice, the dark dead tissue region 1 and the light, recognizable slightly damaged tissue region 2 are displayed in color contrast, so that if for this purpose the color intensity or color level is changed according to the degree of damage , the analyst can perform better and more detailed analysis.

Abstract

In a method and apparatus for improved evaluation of magnetic resonance images, in particular for detection and delineation of endangered brain tissue, a perfusion-weighted MR image and a diffusion-weighted MR image of the same body region are superimposed to form a mismatch image.

Description

technical field [0001] The invention relates to a method for improving the analysis of magnetic resonance images, in particular for identifying and demarcating damaged brain tissue, and to a device for carrying out the method. Background technique [0002] In order to be able to visualize tissue, in particular brain tissue, in detail of interest to the doctor, various MR imaging methods are known, by means of which the respective states of tissue regions can be preferentially visualized with different weights. [0003] In this way, the so-called penumbra or "tissue at risk" is displayed during MR perfusion imaging. Permanently damaged tissue can be visualized very well with MR diffusion-weighted recordings. However, currently these different recordings have to be analyzed by visually comparing the images, which causes great difficulties in practice. Contents of the invention [0004] The technical problem to be solved by the present invention is therefore to provide a me...
