Abstract

The invention discloses a method for constructing an intracranial aneurysm rupture prediction model, which comprises the following steps of: S1, screening out a three-dimensional image data model of a patient meeting prediction conditions from two groups of data of an intracranial aneurysm rupture group and an intracranial aneurysm unrupture group of a patient to be predicted; s2, according to the three-dimensional image data model, obtaining a Dicom-format or STL-format file three-dimensional data model, if the Dicom-format file is the Dicom-format file, converting the Dicom-format file into the STL-format file by adopting Mimics 10.0, and then processing the STL-format file three-dimensional data model by adopting Gemagic studio 2013 to obtain an aneurysm model and a tumor-carrying artery model. According to the method, a traffic mirror image intracranial aneurysm model after rupture is applied, differences of morphology and hemodynamics of a rupture side and an unrupture side are analyzed, and the conclusion that although AR, NWSS, average WSS and LSA are independent risk factors of an IAs rupture state, SR is a parameter most related to IAs rupture, and the risk of aneurysm rupture is high when SR is larger than 1.96 is obtained.

Description

technical field

[0001] The invention relates to a method for constructing a prediction intracranial aneurysm rupture model and the device. Background technique

[0002] Morphological and hemodynamic parameters are associated with rupture of intracranial aneurysms (IAs), and controlling these parameters can help us identify rupture risk characteristics, rupture mirrors posterior communicating artery aneurysms (PComAAs) in the same The patient had a ruptured PCA aneurysm and an unruptured PCA on both sides of the PCA, providing ideal internal control. First, since mirror-image ruptured PComAAs with one ruptured and the other unruptured were from the same patient, the effects of clinical parameters may be balanced separately. Second, mirror-image ruptured PComAAs were located in the posterior communicating arteries on both sides, thus, this could rule out the influence of location on ruptured IAs. Third, in order to improve the accuracy of computational fluid dynamics, indivi...
