The price for a coronary CT is around $2,000. The cost of a coronary CT is related to geography and the level of the hospital. The price varies from county hospitals to provincial hospitals, and generally speaking, higher grade hospitals have higher prices. Coronary CT is now widely used in clinical work. Coronary CT is able to observe the coronary arteries from multiple angles, thus obtaining the stenosis of the coronary arteries, evaluating the risk of myocardial infarction in patients, and effectively distinguishing calcified plaques from non-calcified plaques, as well as evaluating the stability of the plaques under contrast imaging. Coronary CT is a non-invasive examination, which has been widely used in the review of coronary artery bypass grafting and post-interventional therapy to provide imaging evidence for doctors, and should be reasonably examined and treated under the guidance of physicians.
