Bypass blood vessel determination method and system for intracranial extracerebral blood flow reconstruction

Abstract

The embodiment of the invention discloses a multi-modal information guided bypass blood vessel determination method and system for intracranial and extracranial blood flow reconstruction. The method comprises the steps of obtaining a thin-layer magnetic resonance image of the brain of a patient; Obtaining a skull structure model of the brain of the patient; Obtaining a whole-brain angiography image of the brain of the patient to obtain blood vessel structure information of the brain of the patient; Obtaining cerebral blood perfusion and metabolism images of the brain of the patient to obtain metabolism and perfusion level information of the brain of the patient; Obtaining a whole brain neuron electrical activity energy spectrum and a function connection topographic map of the patient to obtain neuron activity level information of the brain of the patient; Fusing the skull structure model, the vascular structure information, the cerebral blood perfusion and metabolism information and the neuron activity level information to obtain a multi-modal stereo image of the brain of the patient; And according to the three-dimensional image, determining an operation area of the brain hemisphere of the patient, and determining an alternative bypass blood vessel. By adopting the method provided by the invention, the selection precision and reasonability of the alternative bypass blood vessels can be improved.

Description

technical field [0001] The present application relates to the technical field of image processing, in particular to a method and system for determining a bypass vessel for intracranial and intracranial blood flow reconstruction. Background technique [0002] In the prior art, intracranial and extracranial blood flow reconstruction (also called cerebral vascular bypass) is a commonly used clinical method for the treatment of ischemic or hemorrhagic cerebrovascular diseases (such as moyamoya disease, intracranial artery occlusion). Its purpose is to anastomose the extracranial artery (the superficial temporal artery commonly used in clinical practice) as the donor vessel with the intracranial artery (recipient vessel, the cortical branch of the middle cerebral artery commonly used in clinical practice) through surgical methods, so as to utilize extracranial blood. It can supply intracranial blood flow, improve cerebral blood perfusion insufficiency, reduce intracranial vascula...

Problems solved by technology

It is often impossible to predict whether there is a suitable recipient vessel before the operation, and it needs to be confirmed after craniotomy
