Abstract:
Objective To explore the application value of dynamic airway computed tomography(DACT)based on retrospective ECG-gating technology in the diagnosis of cardiovascular-related airway stenosis.Methods A retrospective analysis was performed on the bronchoscopy and DACT data of 48 children clinically suspected of having congenital heart disease(CHD)or cardiovascular-related airway stenosis.The image quality of DACT was assessed,and the accuracy differences in diagnosing airway abnormalities between bronchoscopy and DACT were compared.The correlation between DACT and bronchoscopy in diagnosing the degree of airway steno-sis was also evaluated.Results The DACT image quality met diagnostic requirements for all children.There was no significant statistical difference in the diagnosis of airway abnormalities between DACT based on retrospective ECG-gating technology and bronchoscopy.A good correlation was observed between DACT and bronchoscopy in the grading of tracheal stenosis.Conclusion DACT based on retrospective ECG-gating technology can effectively address the issue of motion artifacts in CT scans among infants and young children.It has certain value in clarifying the diagnosis of cardiovascular-related airway stenosis,guiding treatment,and assessing prognosis.
