It is not always possible to cut open the human body to evaluate every small internal ailments. Had it been so easy, God would for sure, have sent us with a zipper in the chest or abdomen so that it becomes easier to look inside. We all want to evaluate the pathologies without having to undergo surgeries or invasive techniques just for the diagnosis and this is where the radiological imaging comes into play. With imaging modalities as ultrasonogram, CT and MRI we can get a good insight of the internal organs in different planes and views non-invasively. With better and advanced imaging modalities, as multislice/ multidetector CTs, it has now become possible to evaluate even the millimeter diametered coronary arteries in a very detailed way non-invasively.

Cardiovascular disease continues to be a leading cause of morbidity and mortality worldwide, making timely and accurate diagnosis crucial for effective treatment and prevention. CT coronary angiography (CTCA) is an imaging modality for non-invasive visualization of the coronary arteries and identification of areas of stenosis or plaque formation. CTCA involves the use of computed tomography (CT) scanning to generate detailed images of the coronary arteries and surrounding structures. Specialized software creates a three-dimensional reconstruction of the heart and its vessels, allowing radiologists to evaluate the degree of stenosis and identify potentially vulnerable plaques in a precise and reliable manner.
