Abstract

Objective: Accuracy of dual-source computed tomography (DSCT) for evaluation of coronary arterial stenosis without heart
rate control.


Material and methods: During 1 year (between January 2012 and December 2012), 108 patients were examined by second-generation dual-source computed tomographycoronary angiography without heart rate control at Radiology Departement
of Bach Mai hospital and underwent conventional coronary angiography. All the data of DSCT were compared with the result
of CCA to assess the sensitivity, specificity and accuracy for evaluation of coronary artery stenoses.
Result: We enrolled 108 patients (65 male, 43 female, mean age 62,9 years). Mean heart rate was 77.4 bpm, radiation dose
was 3.66 mSv. Eighty-four patients (77.8%) had good image quality. Ninety-seven patients (89.8%) were identified as having
significant coronary stenoses. 11 patients (11.2%) having no significant coronary stenoses. Sensitivity, specificity and accuracy
were 93.9%, 93.6% and 93.7%.
Conclusion: DSCT provides a high diagnostic accuracy for evaluation coronary arterial stenosis.
