Validation Analysis Of Plaque Identification And Stenosis Diagnosis By Head And Neck CTA-aided Diagnosis System Based On Artificial Intelligence

Objective:To evaluate the accuracy of the artificial intelligence-based diagnostic system for the analysis of vascular stenosis and plaque in the head and neck,and to explore its clinical application value in the diagnosis and treatment of cerebrovascular diseases.Methods: A retrospective collection of 202 patients who underwent head and neck CTA examinations from January 2018 to October 2021,including 105 patients who received head and neck CTA and head and neck angiography DSA at the same time.All head and neck CTA data were imported into the AI-assisted diagnosis system,and the DSA results were used as the gold standard to evaluate the accuracy of head and neck CTA and AI in diagnosing head and neck artery stenosis,and segmental analysis was performed;head and neck CTA results were used as the gold standard to evaluate AI for head and neck diagnosis.Accuracy of arterial plaque properties,and calculate its specificity,sensitivity and accuracy;draw receiver operating characteristic curves to evaluate the performance of the AI diagnostic system.Results : A retrospective collection of 202 patients who underwent head and neck CTA examinations from January 2018 to October 2021,including 105 patients who received head and neck CTA and head and neck angiography DSA at the same time.All head and neck CTA data were imported into the AI-assisted diagnosis system,and the DSA results were used as the gold standard to evaluate the accuracy of head and neck CTA and AI in diagnosing head and neck artery stenosis,and segmental analysis was performed;head and neck CTA results were used as the gold standard to evaluate AI for head and neck diagnosis.Accuracy of arterial plaque properties,and calculate its specificity,sensitivity and accuracy;draw receiver operating characteristic curves to evaluate the performance of the AI diagnostic system.Conclusion : The artificial intelligence head and carotid artery CTA auxiliary diagnosis system is trustworthy in diagnosing the nature of head and carotid artery plaque and vascular stenosis,especially for severe stenosis and occlusive lesions,and it can effectively improve the work efficiency of radiologists.
