Cardiac MRI & CT

Cardiac MRI

A cardiac MRI is a magnetic resonance scan of the heart. It gives clear pictures of the structure and function of the heart. It can also provide information on signs of angina or coronary blockages. The tests involves lying flat on a bed and being passed through a tunnel, which takes pictures of the heart. Some people can find this a little claustrophobic, but most people manage to tolerate it well.

Heart MRI offers precise evaluation heart structure and function. It provides high-resolution images of heart chambers, heart muscle, and great vessels, enabling detailed assessment. Cardiac MRI is particularly useful in diagnosing previous heart attacks, inflammation of the heart muscle, called myocarditis, or causes of heart failure.
called cardiomyopathies. Additionally, cardiac MRI can help in diagnosis of angina and guide coronary stenting procedures.

Cardiac CT Coronary Angiogram

A cardiac CT (Computed Tomography) is another type of scan that can give information on the structure of the heart and the state of the coronary arteries.

It involves lying on a bed and passing through a “doughnut“ scanner to take picture of the heart and coronaries.

In particular, CT Coronary Angiography (CTCA) is useful in day to day clinical setting. CTCA allows high-resolution images of the coronary arteries, allowing visualization of plaque burden, stenosis, or occlusions, therefore confirming, or excluding furring up of the arteries. Furring up of the coronary arteries with fatty deposits can cause angina, and lead to heart attacks,  CTCA is a non-invasive test and is performed by inserting a cannula and injecting contrast into patients` veins. It takes up to an hour to perform and is usually very well tolerated by patients.
