Feasibility Evaluation of Low Contrast Pulmonary Artery CTA Imaging in Patients with Pulmonary Embolism and the Impact of Applied Dose on Examination Results
Objective to Analyze the clinical feasibility of implementing low-dose pulmonary artery CTA imaging for patients with pulmonary embolism and the impact of radiation dose on clinical examination results.Methods 156 patients with pulmonary embolism admitted to our hospital from October 2019 to April 2023 were selected as the research subjects,and CTA imaging examinations were performed on all patients,According to the random number table method,all patients were divided into a control group(conventional dose)and an observation group(low dose),Observe and compare the MSCT image results of two groups of patients,and evaluate the enhancement of blood vessels and image quality in both groups.Results After comparison,it was found that the doses used in both groups met the clinical evaluation standards,and there was no statistically significant difference in the comparison results(P＞0.05);The enhanced CT values of the main pulmonary artery in the control group were higher than those in the observation group(P＜0.05);There was no statistically significant difference in the optimization rate of image quality between the control group and the observation group(P＞0.05).Conclusion For patients with pulmonary embolism,low-contrast pulmonary artery CTA examination can be performed,and low-dose CTA examination can still obtain ideal image quality,providing objective and reliable pulmonary artery imaging data for clinical diagnosis.
