Problems solved by technology
[0003] At present, most image-based aneurysm automatic detection methods are implemented using deep learning. This method is weak in distinguishing aneurysms from other arterial abnormalities such as vascular branching and vasodilation, and it is easy to misdiagnose other arterial anomalies as aneurysms, resulting in high false positive

The invention discloses an intracranial aneurysm detection method based on magnetic resonance angiography data. The method comprises the following steps: acquiring 3D TOF MRA image data containing the intracranial aneurysm of a subject; preprocessing the acquired image data; carrying out position coding according to the boundary frame coordinates, the length, the width and the height of the marked aneurysm and the artery abnormal area in the image data, and extracting image blocks according to the position codes; taking the extracted image blocks as input of an intracranial aneurysm segmentation model, and taking a manually marked mask as a gold standard to train the model; and performing sliding window processing on a to-be-detected image, dividing the to-be-detected image into a plurality of image blocks, inputting the image blocks into the trained model to predict the probability of the aneurysm, splicing prediction results, selecting a part in an overlapping manner, and taking a maximum value as a final prediction value to obtain a potential intracranial aneurysm segmentation result. The method can quickly and accurately detect and segment potential intracranial aneurysms, and assists doctors in quickly screening the intracranial aneurysms.
Description
technical field [0001] The invention relates to the technical field of medical imaging and computer data processing, in particular to a method, system, device and medium for detecting an intracranial aneurysm based on magnetic resonance angiography data. Background technique [0002] Intracerebral aneurysms are a common and fatal disease with an incidence of 3% of the general population. Ruptured aneurysms can lead to subarachnoid hemorrhage which can lead to high mortality. Early detection of intracranial aneurysms facilitates their measurement and assessment of risk of rupture, which in the clinic facilitates surgical management decisions for unruptured aneurysms. In the detection and imaging technology of intracranial aneurysm, DSA is considered as the evaluation standard, and its shortcoming requires arterial cannulation, which is invasive; non-invasive detection methods include computed tomography angiography (CTA) and non-contrast 3D Time-of-flight magnetic resonance...
