A CT coronary angiogram exam is a combination of CT scanning and contrast dye, used to create multiple detailed images, to evaluate the arteries that supply blood to the heart.
CTA is useful in helping to diagnose and assess conditions such as aneurysms, blockages, injuries, tumours, vessel tears and many more.
What happens during my scan?
Unlike a coronary angiogram, it is a non-invasive is procedure.
If required, an iodine-rich contrast material (dye) is usually injected through a small catheter placed in your arm, before the scan starts.
You will feel a pin prick when the needle is inserted into your vein and will likely have a warm, flushed sensation during the injection of the contrast material.
Some patients report a metallic taste in their mouth that lasts a minute or two. Others feel the need to urinate; however, it is only a sensation and subsides quickly.
To accurately capture the images, you will be positioned correctly on the bed by your radiographer. Once the scan starts the bed won’t move but you will hear noises from the machine as it works
After the scan, the intravenous line will be removed, if one was used.
Once you are finished you can return to your normal activities.
