Adoption of Computed Tomography Image via Nano Contrast Agent in the Diagnosis and Treatment of Arrhythmia Patients

Abstract

To explore the function and specific adoption of nano contrast agent in computed tomography (CT) images of patients with arrhythmia. In this study, the control group received general CT examination, and the test group received preoperative injection of nano contrast agent. All patients were scanned by retrospective electrocardiogram (ECG)-gated helical scanning, after which the coronary artery reconstruction and analysis were performed in a dedicated image post-processing workstation. Compared with the control group, there were decreases in heart rate variability, multistage reconstruction requirement, ECG editing requirement, and the undiagnosed segment ratio during CT scanning in the test group, while the proportion of diagnosable segments and diagnosable patients increased; the average duration of CT image postprocessing in the test group was higher than that in the control group. The nano contrast agent could improve the quality of CT images of some patients with arrhythmia, and the improvement was different in patients with different types of arrhythmia. The overall CT image quality and post-processing of patients with arrhythmia were improved by nano contrast agent, and this experiment laid a foundation for the clinical adoption of nano contrast agent in CT image detection and pointed out the direction for subsequent clinical research.
