Introduction: Cardiovascular diseases (CVD) has the highest prevalence of death worldwide. A myocardial bridge, an anomaly of a coronary artery that is one of the causes of CVDs, are better visualized by Dual Source CT (DSCT) and Coronary Computed Tomography Angiography (CCTA) with > 90% sensitivity and specificity. The CCTA chal- lenge is about tachycardia in a patient who is unresponsive using beta-blockers and produce poor image quality. This study aims to compare the image quality between the systole and diastole phases in DSCT to evaluate the myocardial bridge on patients with tachycardia based on image processing and the size of the bridge between the systole and diastole phases. Methods: ROI was placed along coronary artery lumen and background to obtain quantitative image quality measurement (SNR and CNR). The length, the depth, and the diameter of the myocardial bridge were mea- sured in CPR format. There were 22 samples, consisting of 12 men and ten women. Results: There were significant differences in the SNR, depth, and diameter. Meanwhile, there were no significant differences in the CNR and length between the systole and diastole phases. Conclusion: There was no significant difference in image quality between systole and diastole phases in patients with a myocardial bridge and tachycardia. The length and diameter of the lumen on the diastole phase was greater than that on the systole one. In the other hand, the myocardial bridge on systole phase is deeper than that on the diastole one.
