Problems solved by technology

However, it has been found in practice that this assessment method is only a statistical analysis of the aneurysm patient population, ignoring the analysis of the actual situation of the individual aneurysm patients, so the accuracy of the aneurysm risk assessment is low

Abstract

The invention discloses an intracranial aneurysm rupture risk assessment method and system. The method is applied to the intracranial aneurysm rupture risk assessment method and includes steps: creating a three-dimensional model comprising a parent artery and an aneurysm on the parent artery according to intracranial image data; determining target morphological parameters of a virtual parent artery and a virtual aneurysm on the basis of the three-dimensional model; determining target hemodynamic parameters of the virtual parent artery and the virtual aneurysm on the basis of the three-dimensional model; performing operation on the target morphological parameters, the target hemodynamic parameters and target clinical parameters on the basis of a pre-trained machine learning model to obtaina virtual aneurysm assessment result for assessing aneurysm rupture risks. Therefore, by implementation of the method and the system, accuracy in aneurysm rupture risk assessment can be improved through automatic comprehensive analysis of intracranial aneurysm rupture risks according to clinical parameters, morphological parameters and hemodynamic parameters of intracranial aneurysms of patients.

Description

technical field [0001] The invention relates to the medical technical field of intracranial aneurysm, in particular to a method and system for assessing the rupture risk of intracranial aneurysm. Background technique [0002] Intracranial aneurysm, also known as cerebral hemangioma, is a tumor-like protrusion on the arterial wall formed by abnormal expansion of the lumen of the intracranial artery. It is a common vascular disease. According to statistics, out of every 100 adults in my country, 7 are carriers of aneurysms. Intracranial aneurysms can be divided into non-ruptured aneurysms and ruptured aneurysms. The vast majority of intracranial aneurysms are non-ruptured aneurysms, which generally will not rupture for life, and the annual rupture rate is only 0.05%. However, once a non-ruptured aneurysm ruptures, it will cause spontaneous subarachnoid hemorrhage and become a ruptured aneurysm. The mortality and disability rate exceeds 50%, which seriously threatens the lives...
