Abstract: Objective: Clinical value of dual-source CT coronary angiography in the diagnosis of myocardial bridge Methods: 260 patients with dual-source CT coronary artery angiography in patients with typical angina discomfort, observe the occurrence site, measuring the length and depth of analysis. Results: 260 patients in 62 cases were 70 of the existence of myocardial bridge, detection rate of 20.76%, higher than the rate reported in the literature 18.2%. All of the myocardial bridge were found in the left anterior descending, nearly 17(24.4%), 43 in middle segment(61.4%), 10 in distal segment(14.2%). The average length of myocardial bridge was 15.8 ± 6.4mm, 1.4±0.85mm in depth. Conclusion: Dual-source CT coronary artery imaging because of its convenient noninvasive, not affected by heart rate strictly limit and low prices can be used as an ideal means of screening examination of myocardial bridge.
