It is a diagnostic method that uses X-rays to image the inside of the body. The data obtained by irradiating X-rays from various angles is analyzed by computer to capture a cross section of the body. By stacking these sliced images, the organs can be depicted three-dimensionally from all angles and directions, the organs can be moved on the screen, viewed from the back or bottom, and movies can be reproduced.

The CT scan of the heart can almost accurately diagnose the coronary arteries. Also can be seen size of the aortic aneurysm and whether it is prone to rupture. CT is ideal for observing the progress of stent placement and bypass surgery to widen the stenosis.

What is the difference between CT and MRI?

The greatest feature of cardiac MRI is that it provides a high probability of the presence or absence of coronary artery lesions even if it is completely asymptomatic.  Also can get information on the movement of the heart and blood flow.

Cardiac CT is a very simple and useful test method used in various medical institutions, but it requires various ingenuity to take clear images. In addition, there are problems such as X-ray exposure and risk to the body due to contrast media. and if you want to perform an examination because you are a little uneasy, or if you have a cardiac CT examination at a stage where the initial signs are not clear, it is more risky than the information available. 

On the other hand, cardiac MRI is very difficult to take and analyze, so unfortunately it cannot be performed at any medical facility. In daily medical care, it is important to select a medical facility with solid technology that has accumulated various experiences.

CT and MRI have their advantages and disadvantages due to their respective characteristics. Depending on the symptoms and illness, a combination of both may be used to make an advanced diagnosis.
