The aim of this study was to verify the accuracy of echocardiography by dual-source computed tomography (DSCT). Seven normal beagles underwent DSCT and echocardiography. Echocardiographic measurements were obtained according to the American Society of Echocardiography guidelines. The DSCT images were reconstructed onto the same echocardiographic image plane by using a reconstruction program, and then anatomical measurements were obtained. Nonparametric analysis was used for verifying the significance of each of the measured parameters. The anatomical measurements obtained using echocardiography and DSCT were not significant (P>0.05), and the difference between the measurements obtained using both the methods were within 95% confidence intervals except those for interventricular septal thickness and left ventricular posterior wall thickness in end diastole. The reasons for these differences were considered to be the adjacent structures such as papillary muscles or chordae tendineae that may have influenced the echocardiographic findings, lower far-field image quality of echocardiography, low test-retest reproducibility of echocardiography, high-quality images of DSCT minimizing the motion artifact and the retrospective ECG gating technique of DSCT that offered an adequate timing decision for the systolic and diastolic phase during cardiac movement. Although there were differences in the measurements of interventricular septal thickness and left ventricular posterior wall thickness in end diastole obtained using echocardiography and DSCT, we could conclude that echocardiographic measurement is as accurate and reliable as DSCT for cardiac anatomical assessment.

Background: There is a lack of evidence of the complicated pathways of underlying determinants in the phases of physical activity. The purpose of this study was to evaluate simultaneously a set of potential determinants on the initiation and maintenance phases of leisure-time physical activity (LTPA).Methods: The longitudinal data of 54,359 Korean adults aged 40–69 years from the Health Examinees study were used. The median follow-up duration was 4.2 years. The self-reported durations per week of LTPA was repeatedly assessed. Based on previous longitudinal studies, the potential determinants were selected, and hypothetical models were constructed that consider the complex associations between the determinants. The standardized coefficients for direct and indirect effects were estimated using path analysis to differentiate contributions of mediation from the total effects.Results: In the total population, age, education, chronic diseases, smoking, depression symptoms, and self-rated health were significantly associated with both initiation and maintenance phases. Income (B = 0.025) and social supports (B = 0.019) were associated only with the initiation phase. Waist-to-hip ratio (B = −0.042) and stress (B = −0.035) were associated only with the maintenance phase. After stratifying by sex, the significant effects of education, chronic diseases, and smoking were found only in men. The initiation phase-specific effects of income and social supports and the maintenance phase-specific effects of stress were found only in women. It was estimated that indirect effects contributed approximately 15% of the total effect.Conclusion: The findings suggested that there were initiation- or maintenance-specific determinants of leisure-time physical activity according to sex.
