A Comparative Study About Coronary CTA for Patients with Arrhythmia under Different Time Phase One-Beat Scanning Mode
Objectives: The results of coronary CTA for patients with arrhythmia were compared under different phase One-Beat scanning mode. Methods: 100 patients with arrhythmia were selected and randomly divided into control group and observation group. The relative phase-scanning mode and absolute phase-scanning mode were used for examination. Subjective and objective evaluation methods were used for image quality analysis, while variance analysis and Spearman correlation analysis were used for statistical analysis. Results: The subjective scores of all 13 segments in the observation group were higher than those in the control group, and the differences in 6 segments were statistically significant (P<0.05). CNR values in 3 segments in the observation group were higher than those in the control group, with statistically significant differences (P< 0.05). In the observation group, the correlation between the evaluation data and heart rate was weak (0
