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

Embodiment Construction

[0046] The morphological parameters of intracranial aneurysms are of great significance for the diagnosis of intracranial aneurysms, and the morphological parameters of intracranial aneurysms can be obtained through medical imaging.

[0047] The basic principle of DSA is to digitally input two frames of X-ray images taken before and after the injection of contrast agent into the image computer, and obtain a clear pure vascular image through the process of subtraction, enhancement and re-imaging, and at the same time display the vascular shadow in real time. DSA has the advantages of high contrast resolution, short examination time, less contrast medium consumption, low concentration, significantly reduced X-ray absorption of patients, and film saving. It is of great significance in the clinical diagnosis of vascular diseases. DSA has become the gold standard for the diagnosis of intracranial arterial vascular malformations and aneurysms due to its imaging characteristics.

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 rupture risk assessment result comprises an aneurysm rupture probability; 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...
