Coronary CT angiography (CTA or CCTA) is the use of computed tomography (CT) angiography to assess the coronary arteries of the heart.The patient receives an intravenous injection of radiocontrast and then the heart is scanned using a high speed CT scanner, allowing physicians to assess the extent of occlusion in the coronary arteries, usually in order to diagnose coronary artery disease.
Cardiac CT (CCT) is a modified form of the traditional chest CT due to the difficulty of imaging the complex, moving heart. [16] This is achieved through the use of thin slices and high-resolution scanning, as well as the addition of electrocardiogram (ECG) gating or triggering to capture a motion-free image.
Coronary CT angiography (CCTA) is the use of CT angiography to assess the arteries of the heart. The patient receives an intravenous injection of contrast and then the heart is scanned using a high speed CT scanner. With the advances in CT technology, patients are typically able to be scanned without needing medicines by simply holding their ...
Echocardiography allows detailed structures of the heart, including chamber size, heart function, the valves of the heart, as well as the pericardium (the sac around the heart) to be seen. Echocardiography uses 2D, 3D, and Doppler imaging to create pictures of the heart and visualize the blood flowing through each of the four heart valves ...
In the latter case, the disease creates blockages in the heart's blood supply, leading to tissue death which causes other areas of the heart to work harder, causing the heart to expand in size. [citation needed] Other possible causes include: Heart valve disease; Cardiomyopathy (disease of the heart muscle) [17] Pulmonary hypertension [18]
Cardiac index is a critical parameter in evaluating cardiac performance and the adequacy of tissue perfusion. In healthy adults, the normal range of cardiac index is generally between 2.6 to 4.2 L/min/m².

Cardiac CT and MRI scans: cross-sectional imaging with computed tomography (CT) can help localize and quantify the effusion, especially in a loculated effusion (an effusion contained to one area). [12] CT imaging also helps assess for pericardial pathology (pericardial thickening, constrictive pericarditis, malignancy-associated pericarditis). [1]
