CT Coronary Angiography (CTCA)
A CT coronary angiogram (CTCA) is performed by placing the patient into a CT scanner and injecting intravenous contrast, or dye, into a vein in the hand or arm to visualise the coronary arteries.
The acquired CT data is then analysed to determine whether there are any significant narrowing of the coronary arteries, known as stenoses. If a significant stenosis is suspected, further investigation may be required including ‘functional’ tests for ischaemia, such as a dobutamine stress echocardiogram (DSE), nuclear myocardial perfusion scan (MPS), or direct invasive coronary angiography. Our specialists can organise a CT coronary angiogram after a medical consultation.
