Embodiment 1

[0041] The auxiliary diagnosis method of computerized tomography aortic aneurysm based on deep learning includes the following steps: Step 1: Data collection, firstly, a plurality of ordinary CT scans with aorta are collected retrospectively from the hospital area, and the data are continuous Acquisition, including diagnostic imaging reports and examinations, all acquired images are in DICOM format, including information such as the age, gender, and multiple CT parameters of the patient. In the clinical workflow, the postoperative situation of the aortic stent will be determined by the receiving department In this case, radiologists will pay more attention to the risk of aortic disease in these groups, so that the possibility of missed diagnosis is relatively small. In order to ensure that the aorta of all study subjects is clearly visible on CT scans, In order to more effectively evaluate the effectiveness of auxiliary diagnostic tools, the following data inclusion and exclusi...

Abstract

The invention belongs to the technical field of aortic aneurysm auxiliary diagnosis, and particularly relates to a deep learning-based computed tomography aortic aneurysm auxiliary diagnosis method, which comprises the following steps of: 1, data acquisition: firstly, retrospectively collecting a plurality of common CT scans with aorta from a hospital area of a hospital; 2, data processing: dividing the data into three data sets: a training set, an internal test set and an external test set; and 3, establishing a model, constructing an auxiliary diagnosis tool by using an Attention-Unet convolutional neural network, evaluating the risk, detection sensitivity, specificity and accuracy of the aortic aneurysm in a test set by using the auxiliary diagnosis tool. The method is reasonable in design and has good diagnosis capability on aortic aneurysm; when the method is used in combination with radiologists, the film reading and decision-making capabilities of the radiologists can be remarkably enhanced, and the overall strength of imaging departments is improved. Therefore, the performance of the advanced technology proves that the non-invasive, cheap and convenient method has the potential of clinical tests.

Description

technical field [0001] The invention relates to the technical field of auxiliary diagnosis of aortic aneurysm, in particular to an auxiliary diagnosis method of computerized tomography based on deep learning for aortic aneurysm. Background technique [0002] The aorta is the largest artery in the body. Due to the important position of the aorta in the human body, diseases related to it often endanger the lives of patients. With the development and popularization of imaging diagnostic equipment such as computed tomography (CT), the number of aortic aneurysm cases discovered has increased significantly in recent years, which has attracted the attention of clinicians. Aortic aneurysms mainly include abdominal aortic aneurysm (AAA), thoracic aortic aneurysm confined to the thoracic cavity, and thoracoabdominal aortic aneurysm (TAAA), which grow in both the thoracic and abdominal cavities to account for 5 of all aortic aneurysms. %the following. It has been reported that 50% o...
