Abstract

The embodiment of the invention discloses a magnetic resonance image processing method and device. The method comprises the steps that diffusion weighted imaging scanning and pulse parameter modulation imaging scanning based on chemical exchange saturation transfer are performed on the area of interest of the brain, and a diffusion weighted image and a chemical exchange saturation transfer image are acquired; when the chemical exchange saturation transfer image presents low signal shadow in comparison with the preset benchmark template, arterial spin mark imaging scanning is performed on the area of interest of the brain so as to acquire an arterial spin mark image; the diffusion weighted image is compared with the arterial spin mark image so as to determine a first mismatch area; the diffusion weighted image is compared with the chemical exchange saturation transfer image so as to determine a second mismatch area; and the second mismatch area is removed out of the first mismatch area, and the residual area of the first mismatch area is determined as an ischemic penumbra area. The accuracy of the ischemic penumbra can be enhanced, the image processing flow can be saved, the complexity can be reduced and the safety can be enhanced.

Description

technical field [0001] The present invention relates to the technical field of magnetic resonance imaging, in particular to a magnetic resonance image processing method and device. Background technique [0002] Magnetic resonance imaging (Magnetic Resonance Imaging, MRI) is a biomagnetic nuclear spin imaging technology that has developed rapidly with the development of computer technology, electronic circuit technology, and superconductor technology. It uses magnetic fields and radio frequency pulses to vibrate the hydrogen nuclei (ie H+) in human tissue to generate radio frequency signals, which are processed and imaged by a computer. When an object is placed in a magnetic field, irradiated with appropriate electromagnetic waves to make it resonate, and then the electromagnetic waves released by it are analyzed, the position and type of the nuclei that make up the object can be known. Stereoscopic image. For example, an animation of a serial slice that can be obtained by ...
