It uses multi slice computed tomography, also known as multi detector CT to capture images of coronary arteries after injecting radiocontrast into the blood vessels of the forearm. It can be done as an outpatient procedure.<\/p>\n<p>The scanner captures images timed to contractions and relaxations of the heart triggered by an ECG. For accurate triggering to occur the heart rate has to be stable and low. This is often achieved with the help of medications which are given before the test. Three dimensional reconstructions of the coronary arteries can be obtained by this technique. All the major branches can be seen by CT coronary angio.<\/p>\n<p><em><strong><span style=\"color: #008000;\">What are the downsides of CT coronary angiography?<\/span><\/strong><\/em><\/p>\n<p>Though CT coronary angio is less invasive and quite convenient for the subject, the details obtained are not as good as conventional coronary angio. It is at the best a good screening test to exclude significant coronary artery disease. Once significant coronary artery disease is detected by CT coronary angio, conventional coronary angio is undertaken to decide on what type of treatment &#8211; whether coronary angioplasty (removal of blocks from coronary arteries using balloons and stents) or coronary bypass surgery is needed.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>What is coronary angiography?
