Aneurysm rupture risk assessment method and system

Abstract

The embodiment of the invention discloses an aneurysm rupture risk assessment method and system. The method comprises the steps: converting a to-be-processed three-dimensional DSA image into an imagein an STL format, and measuring an aneurysm morphological parameter of an observed person as first data; acquiring medical record information parameters of the observed person corresponding to the to-be-processed three-dimensional DSA image as second data; inputting the first data and / or the second data into an aneurysm risk assessment model to obtain an aneurysm risk assessment result of the to-be-processed three-dimensional DSA image, wherein the aneurysm risk assessment model is a model obtained by pre-training based on a support vector machine algorithm; and outputting the aneurysm risk assessment result of the to-be-processed three-dimensional DSA image. According to the arterial aneurysm rupture risk assessment method and system, participation of human factors can be eliminated or reduced, consumed time is shortened, arterial aneurysm rupture risk assessment can be simply and rapidly carried out, and an objective basis is provided for arterial aneurysm rupture risk assessment.

Description

technical field [0001] This specification relates to the field of medical imaging and computer technology, in particular to a method and system for assessing the risk of aneurysm rupture. Background technique [0002] Intracranial aneurysms are mostly abnormal bulges that occur on the walls of intracranial arteries. According to reports, the prevalence of unruptured intracranial aneurysms in Chinese adults can be as high as 7%. After rupture, subarachnoid hemorrhage can occur. cause severe disability or death. The treatment of ruptured intracranial aneurysms is mainly to clear the intracranial hematoma and prevent blood from continuing to flow into the brain; unruptured intracranial aneurysms need to formulate individualized management plans based on the results of aneurysm rupture risk assessment and the condition of the patient under observation. Observation or surgical intervention. Therefore, the risk assessment of aneurysm rupture is of great significance. [0003] C...

Problems solved by technology

[0005] The embodiment of this specification provides a method and system for assessing the risk of aneurysm rupture, which is used to solve the following technical problems: in the prior art, the observer uses three-dimensional DSA (Digital subtraction angiography, digital subtraction angiography) contrast images or MRA (Magnetic Resonance Angiography (Magnetic Resonance Angiography) images to observe the shape of aneurysms, combined with the condition of the observed person, to assess the risk of aneurysm rupture, this method often relies on the experience of the observer, is affected by subjective judgment, lacks objective support, and takes a long time
