How it is done?

CT coronary angiography is performed with the use of 16 slice multislice CT scanner with a 0.37sec/3600 rotation time ( Sensation Cardiac 16, Siemens). Patients who have a prescan heart rate > 75 bpm are given b blocker one hour prior to examination in absence of contraindication. You will be asked to lie down on your back on the CT scanning table. A bolus of nonionic contrast media is injected intravenously. Your heart rate is continuously monitored during the procedure with the help of ECG leads. You are asked to hold breath for 15-20 sec during the scan and CT scan data along with ECG tracing are acquired. Soon after the completion of your examination you may resume your normal routine.
