Brief Summary: In this study patients with chest pain lung cancer pulmonary embolism and routine inpatient physical examination were selected as the research objects and the experimental design of retrospective cohort study was adopted to carry out artificial intelligence analysis related to pulmonary vascular diseases in patients with multi-dimensional big data The multi-modal CT acquisition process included plain scan CTNCCT and CT pulmonary angiography CTPA Ctpa-like image effects can be simulated or reconstructed by non-enhanced plain scan CT images so that CTPA-like image quality can be obtained without injecting contrast agent The synthetic CTPA images were further analyzed by artificial intelligence to assist doctors in the intelligent diagnosis of pulmonary vascular diseases
Detailed Description: A non-enhanced plain scan CT image simulates or reconstructs an image effect similar to that of CTPA through the following technical solutions

1 Data acquisition Obtain plain scan CT image data of the examined person including multiple layers of image slices
2 Image preprocessing Preprocessing of plain scan CT images including denoising enhancing contrast and other steps to improve image quality and lay the foundation for subsequent processing
3 Vascular segmentation Advanced image segmentation algorithms such as the deep learning-based segmentation method are used to segment the vascular structure from the preprocessed plain scan CT images The key to this step is to accurately identify and extract vascular areas while reducing interference from non-vascular tissue
4 Blood vessel enhancement For the segmented blood vessel structure a specific image enhancement algorithm is used to enhance blood vessels to make them clearer and more continuous
5 Image synthesis The enhanced vascular image is fused with the original plain scan CT image to generate the final CTPA image During the synthesis process the contrast between blood vessels and surrounding tissues can be adjusted as needed to optimize the display effect
6 Post-processing and evaluation Post-processing of synthesized CTPA images such as smoothing artifact removal etc and quality assessment to ensure that the images meet the needs of clinical diagnosis
