Method for evaluating intracranial aneurysm rupture risk, device and computer equipment

Abstract

The invention relates to a method for evaluating an intracranial aneurysm rupture risk. The method comprises the steps of acquiring image data; acquiring a starting point and a terminal point in a to-be-evaluated blood vessel for obtaining a segment of a target blood vessel; cutting the target blood vessel through a cutting plane for segmenting an aneurysm wall and a vessel wall; performing analysis and acquiring parameter information of the aneurysm and the blood vessel around the aneurysm; distributing the blood flow amount according to the parameter information of the aneurysm and the bloodvessel, and performing blood flow simulation on the blood vessel and the aneurysm through a volume simulating algorithm, and extracting multiple wall surface shearing stress parameters of the aneurysm and the corresponding blood flow dynamic parameter according to a simulating result; acquiring multiple kinds of data of clinical parameters; and performing calculation on the clinical parameter, the multiple wall surface shearing stress parameters of the aneurysm, the corresponding blood flow dynamic parameter and the parameter information of the aneurysm and the blood vessel which bears the aneurysm according to a machine learning algorithm for calculating the aneurysm rupture risk.

Description

technical field [0001] The present application relates to the technical field of intracranial aneurysm rupture risk assessment, in particular to a method, device, and computer equipment for assessing intracranial aneurysm rupture risk. Background technique [0002] Cerebral hemangioma, also known as intracranial aneurysm, is a tumor-like protrusion on the arterial wall formed by abnormal expansion of the intracranial artery lumen. It is a common intracranial vascular disease that occurs in 3% to 7% of the general population. Intracranial hemangiomas can be divided into unruptured hemangioma (UIA) and ruptured hemangioma (RA). The vast majority of hemangiomas are unruptured hemangioma (UIA), which will not rupture for life, and the annual rupture rate is only 0.05%. . However, once the hemangioma ruptures, it will cause spontaneous subarachnoid hemorrhage, and the death and disability rate exceeds 50%. Among the various deaths caused by cerebrovascular diseases, cerebrovas...

AI Technical Summary

Problems solved by technology

However, the calculation of the shape parameters of the aneurysm is cumbersome, and the user has a large operation randomness in the measurement, and the calculation result is inaccurate

Calculation of hemodynamics is more cumbersome and time-consuming. It requires a series of surface reconstruction, grid generation, fluid simulation, and post-processing of flow field results on medical images. For clinicians, it does not have relevant Engineering and algorithm knowledge, inconvenient operation and inaccurate results

At the same time, studies have also shown that the rupture of aneurysms is the result of the joint action of multiple factors, and it is necessary to synthesize multiple analysis results to make an accurate judgment, which is also a huge challenge for clinicians
