Coronary artery CT is a kind of examination method to visualize the coronary arteries through intravenous injection of contrast agent and CT examination. Coronary artery stenosis, coronary artery aneurysm, myocardial bridges and other diseases can be detected through the corresponding examination. 1. Coronary artery stenosis: Through the examination, it can be found that the wall of coronary artery is thickened, calcified, blocked, etc., and the lumen is narrowed, and the degree of stenosis is measured. 2. Coronary artery aneurysm and other vascular malformations: Through coronary artery CT examination, localized sac-like protrusions can be found to diagnose coronary artery aneurysm, and other coronary artery malformations can also be found. 3. Myocardial bridge: Through the examination, it can be found that the coronary artery is partially embedded in the superficial myocardial layer of the myocardium, which belongs to myocardial bridge. Through the examination found that the coronary artery condition is obviously abnormal, further investigation needs to do imaging examination, if necessary, can be directly stenting surgery and other treatments.
