Abstract:
Objective To explore the feasibility of uCT960+wide body detector computed tomography (CT) single cycle coronary angiography in patients with arrhythmia.
Methods From June to December 2020, 63 patients with arrhythmia who underwent coronary CT imaging were selected from the Department of Radiology, Zhongshan Hospital, Fudan University. The clinical data of 63 patients with normal rhythm who underwent coronary CTA at the same time were randomly included.The image quality of coronary artery segments was evaluated by five score method. The contrast to noise ratio (CNR), signal to noise ratio (SNR), aortic root CT value, effective radiation dose (ED) and coronary artery image quality score were compared between the two groups.
Results There was no significant difference in gender and age between the two groups. The difference in heart rate was statistically significant (P < 0.01). The images of all patients could meet the needs of diagnosis, and there was no significant difference in subjective score between the two groups. There was no significant difference in CT value, SNR, and CNR between the two groups. The ED in arrhythmia group was 150% of that in normal rhythm group.
Conclusions There is no difference in image quality of CCTA between normal rhythm people and patients with arrhythmia in uCT960+wide body detector CT, and the radiation dose is acceptable for arrhythmia patient.
